Rather.
MythTV is _designed_ as PVR, timeshifting is the core if it's
functionality. The recording is just timeshifting without reading & cycling
the buffer, the playing is just timeshifting without filling & cycling the
buffer.
The nuppelvideo codec is used, but the stored fileformat is _not_
nupperlvideo but a dedicated format for mythtv.
Anything is possible with open source, but I personally think you should
take another program as your starting point for hacking.
No, that's not the truth, I think you should use mythtv, wait until the
seeking is solved (already in CVS), don't use another player (why should
you: give your friends a copy of linux and mythtv, it's free!)
BTW: everybody uses mythtv to play back files on their computer. It's just
that some of us have their video-out linked to their TV and turned off
their computer monitors. (This was not fully a joke, why would you not use
mythtv to play back the files on your computer, it's the only thing it can do?)
