that's one problem, but converting to rgb for jpeg saving is nothing
short of COMPLETELY IDIOTIC!
it will ruin video in the interlaced case (because of chroma sampling
issues) and just generally hurt quality a lot, converting back and
forth between yuv and rgb.
(in case you didn't know, jpeg is a yuv format!)
