Hi,
PAL used to be 405 lines then became high definition 625! Well that what they said at the time!

I believe that the 15% in USA who don't receive TV via satellite or cable, were not overlooked and the DTV legislation (at least in one proposal) sets up a fund to purchase or subsidize set top boxes for these households.

But -- when you do go HD, it's likely that you guys will be broadcasting H.264/AVC, instead of the lame-o MPEG-2 broadcasts we get here...

Good call Barry! ... And our pictures still won't dissapear beacuse of a simple errant bounced signal.

No more analog TV
No more analog TV
FYI
"Today, the Netherlands rendered "rabbit ears" extinct, becoming the first country in the world to eliminate analog television signals altogether and switch to digital. But it was a largely silent shift, according to a report from the Associated Press, because 94 percent of the Netherlands' 16 million residents already subscribed to cable TV and likely didn't even notice".

in sweden they shut down analog tv this year. Only way to get analog is thru cable provider. Only a few of the channels is in HD, mostly for test but some for serius stuff as well.

This is going to sound nuts. But I far more prefer the look of my old SD CRT TV set than my HD 720p plasma. I dont know why. Maybe its more to do with the magical cathode ray tube than the actual resoloution.

Look at your set's sharpening. Most sets come from the factory grossly, grossly oversharpened, and frankly they look terrible. Turn the sharpening completely off and see if you still hold the same opinion, it might make you happier with your plasma.

CRTs do have better contrast ratios (in good conditions). The contrast ratio makes a big difference on image quality in my opinion. The National Association of Theater Owners also mentions contrast ratio as the #1 factor in image quality (when comparing between film and digital projection). #2 is resolution and #3 is color gamut.
How you measure contrast ratio makes a big difference on the resulting numbers. A lot of LCD manufacturers simple cheap, comparing the brightest white to the darkest black. Since they adjust the backlight when doing this, the measurement isn't particularly meaningful (and broadcast-grade CRTs hit something like 20,000:1 measuring this way). There's also a checkerboard method, but the checkboard's average luminance isn't very representative of real world programming (average luminance is a lot lower). So checkboard measurements are stacked against CRTs- in most situations, CRTs will deliver a better contrast ratio.
The last factor that affects contrast ratio is the amount of light hitting the face of the monitor. If you light the room right, you can avoid that (i.e. shine lights behind the TV, not at the front of it; lighting should be dim).
2- Some HD displays are also limited in resolution due to their native pixels, scaling algorithm, and deinterlacing algorithm (although deinterlacing shouldn't apply to 720p).
Some HD displays are also limited in resolution if you're sitting too far away. Contrast ratio and edge sharpening can also make differences on perceived resolution.
EDIT: Eck, you were talking about plasma.

could that be it? I never thought to try that! Thanks ill give that a go

Actually the Netherlands didn't completely switch to digital. They took the over-the-air analog signal offline. Now the only over-the-air signal is digital.
Cable for most households is still very analog and SD (almost no HD yet). I know, my house in Holland has analog SD cable. Sigh.
I guess it's good my hotel here in California has no HD either, that way I don't miss it at home. But, looking at 4K RED images all day doesn't help either... hehe
