I can successfully use mythtranscode to generate MPEG4 but that overtaxes uses my low powered (800 MHz) CPU (PVR350 only handles MPEG2).  I see the MPEG2 -> MPEG2 transcode, but that seems to only remove segments (commercials) leaving the recording in between untouched (lossless).  I want an MPEG2 -> MPEG2 lossy transcode.

I seriously doubt that.

To the OP, you can also check out nuvexport which has a pretty good UI
and presets that (I think) would do exactly what you need. There's
also Handbrake which has presets and a scriptable CLI you could easily
shoehorn into a user job.
