  You can take a look at my beginnings of a pvr project in CVS at:

  http://www.sf.net/projects/reetpvr/

  One thing I wrote is a simple prediction-based codec.  It's fast
enough for lossless realtime encoding, but the files it writes are
massive (so I can do expensive tasks like resampling and 3:2 pulldown
inversion using off-line algorithms).  You can check out the code for
this codec extracted from reetpvr at:

  Currently my pvr is misnamed: it's just a high-quality v4l recorder.
But it has a few unique bits: I record closed captions, the lossless
compressor, I run SCHED_FIFO, I correctly calculate audio drift, I can
record at full frame size, and I reverse 3:2 pulldown.

  Hope I can help,
