If I had to hazard a guess, if you're using SPDIF then the PCM clock
on the set top box is dropping, and the encoder in the HD-PVR probably
has an issue with clock recovery.
This might be fixed in a newer firmware, although there is a known
issue with the latest firmware that requires a driver fix (and to my
knowledge, nobody has taken up the task of doing it).
