Hi Andrew.

Pretty much every one of the failures is the result of the STB doing
something unexpected.  The HD-PVR(1) does not recover from the unexpected
well at all.  If you tell it to "start encoding" while the STB is still
trying to get its act together, you will not end up with a good recording.
I am hoping the HD-PVR(2) handles such situations better.

For reference, I am using Directv H20 STBs.  They are pretty old at this
point, but they have optical S/PDIF and I have never had any problem with
audio/video sync with Dolby Digital.
