[mythtv-users] LiveTV fails

I have encountered a weird error, that occurs when I try to watch live tv.

When I enter "Watch TV", the screen is black for about two seconds. 
After that, I can watch TV just fine for a few seconds, before it starts 
to "lag", and quickly entirely freeze.

Below is the output from mythfrontend (normal -v setting). The backend 
(more verbose) does not report any errors.

Using myth0.9.3 (SVN) on Debian testing (2.6.16.20), with a PVR-350 (in 
and out) and PVR-500 (unused in this setting).

And by the way - the file is written fine, and the permissions are ok 
(frontend and backend are running as same user mythtv). The filesystem 
is JFS.

Thank you in advance

/ Henrik
