That's very interesting, since I've just been experimenting with 
recording from my bt878 card using bttv and mencoder. I'd been setting 
it to YV12, since that's what most codecs seem to want. The image looks 
fine, but detc doesn't work perfectly on film sources. It mostly works, 
but there are jerks and comb artifacts every once in a while. I assumed 
it was just because of noise. Do you think it will work better if I use 
YUY2?
