The digital tuner will put exactly what comes over the air into the file, which
will be mpeg2 but the bitrate and resolution will be too high (on all but the
SD
recordings-which will probably have the audio out of sync on the) for the mvpmc
to play. I don't record off of my analog portion of the 5500 as I have 2
other pvr150 tuners (which produce mpeg2 that works fine on the mvpmc), I have
a
script to transcode the non-mpeg2 (or too high of resolution) stuff down to
formats and resolutions that will work with the mvpmc, it does take 30-60
minutes (maybe more if your machine is slow) to transcode, but it puts the file
back in place of the original nuv file and mvpmc works fine with that.

No it won't play it. It will either be mpeg4 or rjpeg depending on what
settings you have in mythtv on that recording card, and mvpmc cannot play
either
of them.

I have a script I run as a user job in myth that converts and puts it back into
place of the original file so mvpmc can deal with it, it uses mplayer to do the
convertion, I believe with a new enough version of mplayer it will handle nuv
files, it does reliably handle the high-[bitrate,resolution] mpeg2 streams.
If you want the script, ask and I will post it again.
