I'm not getting any mail from this mailing list :( It would be nicer if the
replies would go both author and the mailing list... fortunately archives
work.

Yes, you're right about the card and the capture format. So I'm somewhat
surprised that with pp=md the colors get quite correct actually.

The problem with capturing in 4:2:2 is that mplayer doesn't support 4:2:2
Quicktimes.

(It doesn't really support 4:2:0 format either but at least I succeeded
making a patch for that format... although it wasn't accepted)

And no, I won't use mencoder for capturing into AVIs because I want the
video in Quicktime format so that I can edit it with Bcast2000.

For Ville Saari: thanks for the patch. I'll try it sometime. (I was
planning to write such a thing myself but you saved me from that work).
