I have isolated the problem now.

In VDR 0.82 the cDvbApi::SetPid() function made the DMX_SET_PES_FILTER
call even if the Pid value was 0. Apparently that didn't hurt with previous
driver versions, but it looks like it does hurt (at least for encrypted channels)
with the newest driver. This function was called with a 0 Pid value for instance
if the Pids were set for "non recording", in which case the second audio Pid
doesn't have to be set.

I have now changed this so that the DMX_SET_PES_FILTER call is no longer
made if the Pid is 0, and that seems to work. So it was my fault, not the
driver's.
