I see that on 6629 I have the same problem. I am not sure on which driver version I tested, but I was under impression that it worked with a bad overscan.

I think Faroudja chips are not so good. At least my Philips LCD TV has such chip, and everytime text is scrolling Faroudja's autosensing goes wrong, and on scrolling text I get bad combing and also picture judders a couple of times when format changes. Luckily on my projector I can control deinterlacing by turning off "film" mode deinterlace (so just use video deinterlace), so video material from VDR always runs smoothly. My LCD doesn't allow this. I see that this is problem of my TV, but if Faroudja was good it would not do this.

HTPC also can read MPEG streams flags to aid deinterlacing/inverse telecine, and Faroudja's don't have that stuff because they are behind video line on TVs/projectors.

Best regards, Jori
