Avidemux can hack out your commercials, save MPEG2PS, and essentially do
a fast copy of the streams if you aren't changing scale/format. 

Trimming commercials out should not require reencoding at ALL if you
want an MPEG2 out, and have a MPEG2 nuv from a 250/350/m179.

I don't know if encoding is involved to generate MPEG2PS from normal,
same size MPEG2, or if it is sort of a "recompile". I suspect the

Avidemux2 will also directly load mythtvs flavor of nuv file , rtjpeg,
mpeg2, or mpeg4 based, and allow you to trim out the commercials and
encode ONCE.

Mythtranscode or old unsupported versions of mplayer are not required.
