since upgrading to the most recent Ubuntu release 8.10 (Intrepid), my FF
card is having problems. It is async with audio, both for some live TV
channels and some recordings. It is also skipping while watching live
TV. (This is not a full diagnosis, but the skipping appears to be
limited to encrypted channels.) 
vdr didn't show this behaviour with the previous setup (based on Hardy
with default Ubuntu kernel).
However, the logs show nothing. Nothing at all.
So how can I debug this if the system thinks that everything is fine?
Here's the setup:
Athlon X2 CPU
vdr 1.6.0-2 e-tobi binary for Ubuntu 
(e-tobi version number: 1.6.0-8)
Budget DVB-C card used as input,
with CAM and Kabel Deutschland smartcard,
using the driver that comes with Ubuntu's default 2.6.27 kernel
FF DVB-C card without CAM, used as input and output,
using the ttpci driver that comes with Ubuntu's default 2.6.27 kernel
plus the modified firmware from
