I upgraded from a TNT to a gf4 mx440, and for one video playback looks noticably worse. A quick search turned up this thread, which mentions different cards may use different resampling methods when playing video full screen.
Video cards: bicubic resampling / Mod32 / VIA chipsets (http://forum.doom9.org/showthread.php?s=&threadid=12507&highlight=video+playback+bilinear)
What I'm thinking is that my old TNT used bilinear sampling and the gf4 mx uses bicubic, which would explain the differences in playback quality. The thing is, I liked the bilinear. It hid alot of the imerfections. I've been encoding clips from tv captures all this time with the TNT thinking "tra la la, this looks great. No artifacting", then I watch them with the gf4 mx and the blending that was covering up the artifacting is gone. I now see all the macroblocks in horrid detail. Am I right in this line of thinking, is it different sampling methods causing the differences in playback quality? And if so, how can I force other methods used (like if I wanted to go back to bilinear)?
