I thought I had understood the "4:2:0" notation, but now I'm completely confused. Do you have (a link to) a good explanation of it?
Here's a pretty good glossary of video terms: http://www.dvdmadeeasy.com/glossary/special.html
Ok, according to that I had it right. if Y is 240*320, then U is 120*160 and V is 120*160. There's no 60*160 involved...
... unless you have interlacing as well (which I assume is *not* the case. I know incoming video is, but isn't that deinterlaced before the input card gives a frame ?)
