If the card uses YUV 4:1:1 or YUV 4:2:2 the Phillips chip pair should be the somethng like 7911 and 7912, at least as far I remember it and it could also be the old pair, used as I described it in my earlier emails. I can look the stuff up, some friends of mine build their own card. They still build MPEG stuff now, for gas station monitoring for example. Ulf.
