I want to take a standard MPEG2 HD recording (from my HD5500) and transcode it down to a version that my PVR350 will play on a 
standard analog TV.  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.

With the forced march to digital source and all the PVR350's out there I can't believe I'm the only one wanting to do this for 
backup/workshop viewing.  Any ideas?

I am also interested in this concept, however perhaps with more CPU, using HD H264 files and maybe even having simultaneous output 
from a front-end - over HD / component via an NVIDIA >= 8000 card - and a PVR350 outputting the same (downscaled) content over 
composite.  (Or alternatively a 2nd NVIDIA on PCI?)  Any one able to advance this?
