Judging from the number of error messages that IE (5) reports when
loading that page, there are some serious problems on the sending side
of that site. I don't think it's our software.
Too bad; the content over there is intriguing.
(By the way, the URL that eventually loads is
http://www.candlepowerforums.com/vb/portal/index.php. Is that correct?)

Oh no, only if you want to post there.
You can , without login read all of it.
The site is a nice demo, opening a thread is dead slowwww......

My AVG-free is free to update when needed, everything else is turned off,
that means everything that I can find and manually turn off.
This hack/spit Vista (still just an incomplete W 3.1) machine is about 5
years old, and from the first day of use, before attaching the (modem line
at the time) cable for internet access, I shut off all of the "phone home"
and "report this" and check for updates crap that I could find.
I rarely install anything I've heard or read about, couldn't give a FRA

Thanks for that.
Now that I've got you on the line, can I make a request of you? Could
you please not top-post? If you look, you'll see that, like, 99.9% of
posters here bottom post.
Now, I know you're a wild guy and all and don't want to be tied down by
boring convention, but this is one that actually makes sense.
Anyhow, just a request.

How to backup Thunderbird email and settings:
<http://www.iopus.com/guides/thunderbird-backup.htm>
There are also programs and plug-ins to make it easier:
<http://www.freeemailtutorials.com/mozillaThunderbird/backupRestore.cwd>
<http://mozbackup.jasnapaka.com>
etc.
Personally, I don't like any of these methods. I run image backups of
the entire hard disk to either a USB drive or over the network to my
NAS (network attached storage) box. This weeks favorite is Acronis
True Image Home 2011.

Same here, but with one difference. I do computer support as a
business and find that it is important to experience upgrades and
other disasters prior to when my customers experience the same
problems. This way, I can answer the panic calls intelligently. For
example:
<http://forums.avg.com/ww-en/avg-free-forum?sec=thread&act=show&id=132999>
Oops(tm).
To give you a better perspective of what you're attempting, try going
through an entire day without making any mistakes. Everything has to
work perfectly at the first attempt. That's not easy to do, even
consciously. If you try it for an extended period, you'll find that
paranoia is the inevitable result, where you do nothing rather than
risk failure. You can't run your life that way, and you should not
try to run your computer that way. If you want to minimize risk, but
not eliminate it completely, it might be best to DELAY upgrades,
instead of ignoring them.

My customers sometimes ask me "is it time to upgrade"? It's a silly
question because the answer is always obvious. When the machine
becomes painful to use, won't do certain things, and burns time like
the government burns tax revenue, then it's obviously time to upgrade.
I still have machines running W2K because I'm cheap and they're not
worth the cost of an XP license. However, if money is the problem,
then a major upgrade to 3.5GB RAM (the maximum for a 32 bit OS) would
cost you the least.
Incidentally, I'm now resurrecting a Thinkpad X30 PIII/1.2GHz laptop
that looks like it was probably last used as a frizbee.
Dr Frankenstein's monster looked better after I glued everything
together with globs of epoxy. Still, it runs XP SP3 quite nicely, so
it will probably find some use, somewhere.

I'll call your 5 and raise you to 11 errors. Go thee unto:
<http://validator.w3.org>

The errors look like they're coming from the CMS (content manglement

I respect your courteous request David, as they're generally accompanied by
numerous names and pissy remarks. Or they just filter me, but that's their
privilege.
Bottom posting isn't sensible, or I would have been doing it for the last
12-14 years.
So you see, this is my conventional method.
I've always top-posted for the obvious reason.. convenience for others.
Before scroll mice, it was even slower to get to the bottom of a post to see
a reply.
If you look at a typical thread that's been receiving replies for a couple
of days, there is a lot of previously read junk to scroll down thru to get
to a reply that may be a couple of words. It simply amounts to a lot of
wasted time.
So your position is that everyone should waste that time, because of some
outdated method based on the early BBS networks, correct?
When early online communication began, there were a lot of really slow
connections in the networks, and top posting could've been annoying, when
seeing a post start with a reply at the top because the original post hadn't
made it's way to all points in the network.
Those days are essentially gone forever. If anyone still isn't getting
quality feeds for newsgroups, they should find another service. This APN is
only $3/mo.
After all.. I was replying to you, and you probably knew exactly what the
reply was in regard to, yes?
Years ago, with much less stable feeds, I often encountered dropped
messages, but even then, reading a couple of other replies would reveal the
details of the original post.
Many posters quote everything sent previously by others. After several days,
there is a huge mess to go past, to see a reply.
Trimming previous replies from earlier posts is apparently too much work for
them, and finding the reply comments is often tedious.
As you can see, I've trimmed the previous post, since I'm addressing a
different topic, but there was no need to scroll down past it.

No, it's because there's this advanced technique called "trimming",
which I just demonstrated here. No need to mindlessly copy every part of
a message in a deeply-nested thread. Duh.

I fully agree with your demonstration of trimming, which I had also done and
explained, however it was snipped.
You and I could describe and demonstrate trimming endlessly, and it won't
convince the typical usenet user to trim posts before sending them.
The majority are just too lazy and/or inconsiderate, which no amount of
exchanges will change.

You said earlier, "This does not sound like a modulator issue", but it seems
to be one to me. I'm not familar with that model but many vcr's get the
audio/video feed into the modulator from the a/v jacks, or the same path.
So generally if you have composite working but no r/f, it's something with
the modulator.
Also, are you sure the vcr is the one producing the blue screen? Most tv's
within the last couple decades go to blue screen if no rf signal is present
on a channel.
If the modulator is dead, or not getting power, would make sense with the
blue screen.
Generally modulators have a switched 5 or 12 volts fed to them when "on".
Usually only 5 or 6 pins.
Without a schematic, I'd just use a volt meter, touch each pin while
switching it from "tv" to "vcr" mode, one of them should swing from
next-to-nothing to +5 or +12.
If none do, it's in the switch circuit (schematic needed at this point), if
one pin does, it's probably the modulator. Would only take a few seconds at
this point with a scope to see if video and audio is present at the other
pins.
Basically, if you have power, video and audio going into the modulator and
nothing out, it's a bad modulator.
My guess is, if it was working and stopped working after a couple weeks with
the new owner, likely there is something he isn't telling you.
Many "bad" modulators went bad right after the owner tried to do something,
forced a cable in, bent pin, yanked the cable hard.
Many a modulator gets the center of the "out" jack cracked or broken off the
circuit board inside of it. Too little pad for too big of a connection. Any
abnormal force breaks it.
The hardest part to all of this is just gaining access to the modulator,
some are a peice of cake, some a pain in the ass.
But I'd still guess "something happend" when "it just quit working".

Have you tried it with more than one television? If using a current model
equipped with an ATSC tuner, the NTSC is an afterthought, and often requires
a "perfect" signal to operate. VCR modulators are very crude devices, with
no appreciable filtering (the audio signal can be seen on both sides of the
carrier, there is no vestigial sideband filtering) which can cause the TV to
lock in to the wrong part of the signal (i.e. lock onto the first carrier it
sees: the audio carrier that shows up at the bottom of the 10 MHz wide
output channel).
Lots of incompatibility issues with the new generation of TV's..

I just got a similar unit about a week ago, and you won't likely know what's
inside until you open the case.
The Schumacher Instant Power 400 Peak Amps model IP-55 has a 12V 5Ah battery
and an internal charging circuit (AC transformer, circuit board, LEDs
red-yel-grn).
On the back of the unit, there is a flip-up set of (2) blades that fit a
standard NEMA 120VAC extension cord female connector. Any AC cord is just
connected to the 2 blades for charging.
The manual states that an optional 12V cord is available for charging from a
car lighter-socket "while driving" (inserted into the front DC power outlet
socket), which won't actually work well unless connected "while driving"
while the vehicle alternator is operating and the output voltage is about
13.8-14.2V.
Cable p/n 38-99-001564, which doesn't seem to exist.. not found on their
site or by Goog search.
A warning cautions that the unit's internal charge limiting circuit is not
applied when the adapter cord is in use, and the charge-level LEDs aren't
functional/reliable, so.. the user needs to disconnect the adapter cord and
check the level of charge frequently when using the charging cord, also
never used in excess of 4 hours, never unattended - risk of explosion or
fire, and disconnected when the engine is not running.
The unit's internal battery is connected directly to the big, external
battery terminal clamps, so one needs to avoid contacting the clamps to
anything conductive, or each other.
The front DC power outlet is connected directly to the internal battery,
with a 15A self-resetting circuit breaker in series.
Charging thru the front power outlet socket on these types of power-packs
should only be performed by use of an actual smart/automatic battery
charger.. one that will charge at a low rate (~1A maximum for a 5Ah battery
or C/0.2 rate) and capable of automatically stopping the charge cycle when a
fully charged state is attained.

No need to pay silly prices for a sophisticated battery charger. Lidl and
Aldi in the UK both do similar ones for about 14 gbp. They pulse charge a
flat battery, change to a normal charge, then switch to a maintenance one.
Get the same thing with a 'name' on it and you'll pay four times as much.
