Don,

Thanks a lot for the eye-opener. I would not have guessed that the DVI pick-off point was after the deinterlacer.

This means the same old on-going discussions about quality of decoding, 3:2 pull-down, and deinterlacing are just as important for DVI players as pure analog players - I think?

Then why so little mention of this in the discussions about DVI and how it "looks so good" on fixed-pixel displays, with very little or no mention of the usual artifacts, jaggies, chroma bug, combing, video/film mode-switching problems, etc., etc., that can result from mediocre MPEG decoding, 3:2 pull-down, and non-Faroudja/Silicon Image deinterlacing??

For instance, does the D1 employ very good decoding, 3:2 pull-down detection, and deinterlacing?

It seems like that whatever makes an analog video DVD player (discounting the VDAC's and video channel) have reference PQ is also what should be started with to make a great DVI player.

I'm getting the impression that some newbies to DVI may think bits is bits and therefore any ole' DVI player will do.
