This should work as is today (asusming everything is set up properly)
Specifically (for CVS version), you need TranscoderUseCutlist set to 1,
and MaxTranscoders >= 1
The Transcoder needs to be set to use MPEG4 or RTJpeg

The only cutlist which is supported is the manual one (so the
auto-commercial detect stuff won't be used)

I don't have a PVR-250 setup yet, so I can't test it, but it should work.
 If not, it is a bug.

As of 0.10, the command should be:
mythtranscode -p transcode -c 1047 -s 2003-07-15-11-00-00

I will only support transcoder issues with recent CVS, as many changes
have occured recently.

You should have the Transcoder set to use MPEG-4 or RTJPEG, not MJPEG
