I read the following which had been posted on the DVD forum about possible problems with HD screens and upscaling DVD players and I wonder if anyone can clarify, confirm or explain (I know the post is about PHD7s but it seems relevant to other HD screens, including the PHD8. Does any of it still apply?):
I'm planning on getting an HD DVD player (or Bluray, whatever) when those hit a bearable price, but wondered if perhaps a prog scan player - possibly with upscaling to take more strain off the panel's processing - would give me better PQ than my trusty old SD-220. I'd seen some good reports about the Pio 575 and Samsung 850 and thought that £100 or so might be worth spending to tide me over. My reading of the above is that this would NOT be the case.I toyed with the idea of buying a HD7, but decided against it after I did a bit of research regarding image scaling.
Isn't there a problem when upscaling and not using a 1:1 resolution match?
Using upscaling DVD players on 768 line screens you would have to get the player to upscale the image to 720, then the screen would scale it again to 768.
I thought double scaling was a no-no and introduced all sorts of nasty things like increased macroblocking etc?
If it was a 720 line screen then that would be a different kettle of fish.
