I think Dale was talking about transcoding the MPEG-4 produced by his
Plextor to MPEG-2. If so, the lossless transcoding won't work, because
it requires an initial input of MPEG-2 for an output of MPEG-2 having
removed only sections of the video (thus the losslessness ;).
So, it sounds like he'll have to wait until you've got your transcode
MPEG-4/MPEG-2/RTJPEG to MPEG-2 work complete.
