Carl, thanks. It's helpful o know hat something _should_ work when 
dealing with many alternaives.  I updated to the latest drivers from 
Nvidia and now vdapu works.

Alas, my problem still exists. But as the buffer problem has been 
resolved, I need to be more specific. 

There are two things, perhaps related, although I think not.

First audio leads video by several seconds; I've been able to improve 
but not eliminate that be tweaking -mc.

Second, after some minutes, I hear sharp cracks in the audio stream. I 
can eliminate them temporarily by seeking forward a bit. I would guess 
that "a52: CRC check failed!" marks the problem. Any thoughs?

Here's the log:
