Your display will either upconvert or downconvert the image, that's true. Some people (one guy in particular who I'm not going to name) insists that 1440x960 is the only worthwhile resolution to watch DVD's on. All other resolutions are a waste of time. http://www.avsforum.com/ubb/wink.gif
Well, I don't believe that and if you saw an anamorphic DVD at 848x480 and compared it to 640x480 on the same display, I think you would hands down prefer 848x480. All things being equal
(which almost never happens in real home theater life), I think XGA looks better than SVGA resolution. Upconverting should soften the image. Irregardless, I think it looks better. I think it's funny how D-ILA owners have turned this thread into an "MPAA is Borking HDTV" conspiracy. I'm not saying they're wrong, I just think it's funny. How much ya wanna bet that if D-ILA's could
do 1440x960, we'd read post after post about how quadrupled DVD is the only way to go
Just an observation. Btw, I'm not saying their remarks are wrong or their concerns aren't valid. Just weird how good news for one technology (DLP) is bad news for the other camp (D-ILA).
Defiler, what I didn't mention before is that a non anamorphic DVD will have around 270 vertical lines. TV sets can handle this without downconverting the image. This is part of why some people said non-anamorphic was better than anamorphic: it looked better on cheap TV's. The reason being that the downconversion of anamorphic DVD's on old DVD players (still maybe?) wasn't good. Lot's of aliasing and jaggies. Anyway, on an SVGA display, the 2.35:1 window is 800x340. This is enough to show a non anamorphic 2.35:1 DVD with no downconversion, but anamorphic 2.35:1 DVD's are shown with 20 image lines thrown away. To make a long story short, you have to look at the 16:9 window within a display to determine whether there will be downconversion or upconversion (I haven't seen pixel perfect 720x480 DVD, yet). For anamorphic DVD's, if the 16:9 window is less than 480 lines tall, there will be downconversion. If it's greater than 480 lines, there will be upconversion.
16:9 window within 800x600 SVGA panel = 800x450 (800/16:9 = 450) downconversion
16:9 window within 1024x768 XGA panel = 1024x576 (1024/16:9 = 576) upconversion
