I have solved this, but I don't really understand the solution.

The recording profile for transcoding included "Autodetect MPEG", which what 
configured to use the RTJPeg codec. As an experiment, I changed this to use 
the MPEG4 codec, and that solved the problem.

I found a Knoppmyth forum post that explained that there was no point in 
transcoding MPEG2 to RTJpeg, because MPEG2 is better compression anyway.  I 
understand that (I guess RTjpeg is just frame-by-frame JPEG compression or 
something?), but it's not clear to me why it would fail to work, even if it 
isn't useful.

Any light you could shed would be appreciated,
