[mythtv] Questions on how PVR-350 playback works.

I have a few questions on how playback works for the PVR-350, with a eye
toward smoother fast-forward, rewind behavior in the future.
How does normal playback work. Does MythTV simply send the mpeg (.nuv)
file unmodified to /dev/video16?
How does fast forward at the first setting (3x) work. Does it use the
hardware ability to play MPEG at high speed. What about higher settings?
Does it continue to use the hardware (can it even handle it) or does it
only send it parts of the mpeg file. If the latter does it attempt to
parse the MPEG file to pull out the I frames and only send it them or does
it simply skip ahead in the MPEG file and fixed intervals and have it play
back small segments?
What about playing in reverse?
Thanks in advance.
