I dont mind watching stretch o vision on the HD channels mainly because it is still better pq than the actual SD version of the channel.
That's not the point. If they just took the SD picture and upconverted it (like the networks do), leaving it 4:3, it would look great. Why take the extra step of distorting it?
All the close ups of people make them look like they have encephalitis. Also, it makes me queasy when they pan and the background starts to "flex." I think it's nearly unwatchable most of the time.
The Scripps channels don't seem quite as bad as the Turner ones. They annoy me, but not enough to specifically tune down to the SD versions.
If they must screw with the, picture, I'd rather have them do it like Discovery, even though we lose the top and bottom edges. I honestly never notice there a problem on Discovery until the credits come on and I can see the bottom edge crop. I've never see a head get cut off or anything like that.
