Dora looks more alert? Bush looks less blue in HD?

Good question. I don't think there's anything stopping transmission in 720  
instead of 1080. I believe Sky's own channels are 1080i but some of the  
non-Sky HD stuff is 720p. As for discs If they're going to the bother I  
don't see why they'd only use 720 over 1080. For games, I note some for  
the PS3 only go as high as 720. A decent decoder will up/down scale  
according to the TVs abilities, but obviously the more data the better.

Well one is live the other cartoon (feel free to guess which is which),  
you should also rezoom them so they have the same apparent height (if the  
browser hasn't), and I believe Dora is NTSC which uses less lines then PAL.

Nope.

	There's a big difference - the folks in the shop probably had not set
it up correctly, or something.

	What I've disliked about big HDTV's is that regular channels, DVDs, etc
can tend to look quite poor on them. This is _not_ in comparison to
looking at HDTV feeds. Probably just because the TV's I saw were quite
big (in inches), so you could easily see all the flaws of regular TV
shows...

It was either National Geographic HD or Discovery HD which I saw at the
store here in Finland (Verkkokauppa.com is the store) from multiple
HD-screens at once. I couldn't figure out if the resolutions seemd to be
good or bad, 'cause I almost got a headache from the infernally bad
MPEG-encoding! Seriously, I'd take old-fashion analog-RF rather than
such crap, while the analog problems are easier for brains to filter.

That's a sign of bad TV or bad TV-out. I had 25" Finlux (some
basic-model, but good picture quality) and Matrox G550 connected via
S-video: Windows desktop was usable (no, not clear, but useable) even
with 1280x960. It was unbelievably clear with 800x600 (didn't outperfom
a monitor, but I was really surprised that a TV could do that).

> I think we've established that the shop was overpriced. ;-)

Certainly ;).

And yes, SD-picture seems soft when watched with 93" picture from 5
meters away. I think that (really a big picture with home theatre
enthustians) is a real winner-goal for HD. 768x576 vs. 1920x1080 makes
pretty big difference, once you can see the pixels of the first one.

Where the hell are you shopping? I priced LCD HD TVs last weekend, and I
could get a good one for R7000. (that's somewhere around 450 pounds, if you
convert)

Odd. I often plug my laptop into my 6 year old TV, since I also don't have a
DVD player. At 800*600, the desktop is easily visible and the text readable.
It's not as clear as on the laptop screen, but then I wouldn't expect it to
be.
