[mythtv] less CPU-intensive MPEG-2 decoding in CVS

Just a quick announcement about a recently added feature:
The latest CVS now includes a version of libmpeg2
(http://libmpeg2.sourceforge.net) as an alternative to the FFMpeg-based
video decoding. FFMpeg still handles the demuxing, but the video can be
handed to libmpeg2 instead. This takes significantly less CPU on my
test machines, so it's good for lower-end systems; my 450MHz Cube can
finally handle SDTV.
If you use MPEG-2 video and want to try this out, enable the "Use
libmpeg2 for video decoding" on the first screen of Playback settings
-- it's disabled by default, so you'll have to explicitly enable it.
Also, you must have XvMC turned off; right now, the libmpeg2 path won't
work with XvMC, and forces FFMpeg decoding instead.
