This only applies to replaying a recording with the DVB card, right? I
noticed that a couple of times, too. I think this happens when there is
not enough disk i/o bandwith left for the replay thread on a heavily
loaded system so - from my point of view - this is no bug or design
problem.

If you have enough RAM in your system, you can probably get around this my
enlarging VDR's internal buffer (someone else recently posted a message on
how to do this).
