Hi chenzhaoyi,
I think there are three contributors to this:
1. Lots of hdtv sourced material is incorrectly flagged as 1080i/60 not 1080i/24 film, as mosy dvd software players are flag reading, they don't get a film-mode lock (i.e. can't switch on 3-2 pulldown removal).
2. Apparently most video drivers do a poor job of deinterlacing 1080i material. I think the Nvidia 6600 card and ATI 1300 with latest drivers are reported to have a n automatic "smart" cadence based film-mode lock.
3. Many hdtv captures have dropouts that cause the deinterlacer problems and hence occasional combing.
Some 1080i films look good on my Radeon 9700 Pro (cat5.12), but most looks poor. Test plates reveal that the graphics card is dropping half the vertical resolution anyway, even when outputting at 1920x1080p.
This is comparing to a Roku HD1000 set-top player outputting natively at 1080i/60.
Conversely, 720p on the HTPC doesn't need deinterlacing so always looks fantastic.
regards,
Rob.
