Interlacing? Radeon 9000 w/ PAL feed. - Tilted Forum Project Discussion Community

Got a Sapphire's Radeon 9000 Pro Atlantis 64MB DDR Vivo card as a gift and crammed it in today. All around excellent a card, but one problem persists.

I own a European playstation, and hooked it into the card hoping that it could display the PAL signal. Well, it does, the colours are wonderful and all that jazz...however the picture jitters. It doesn't jitter as badly or anywhere near as badly as when I try to hook the psx to an NTSC tv set, though. I am thinking maybe it's a problem with interlacing, but since I am not terribly familiar with the concept, I cannot be sure. ATI's MMC 7 does not seem to allow/have de-interlacing, so I am hoping that someone might have some ideas as to how to find a workaround for this.

What made me think it might be interlacing-related, was that I tried playing Final Fantasy VII for a bit, and whenever I would move the character down the screen vertically, the jittering would stop for the duration of the movement. Does this mean anything to any of you? Please share any hints and tips, as I really would like this to work.

<small>Btw, sorry if I've been posting a lot of threads as of late. This is an exceptionally helpful board, is all.</small>
