Hi

Something that has been driving me nuts since I installed a frontend
machine a few months ago.

Every once in a while (about 3 hours), LiveTV will freeze. I have to
exit and go back into LiveTV.

I just captured in the log what would appear, and I see on the frontend log:
2009-01-22 09:20:03.188 NVP: prebuffering pause
2009-01-22 09:20:03.190 WriteAudio: buffer underrun
2009-01-22 09:20:04.968 NVP: Prebuffer wait timed out 10 times.

2009-01-22 09:20:17.568 NVP: Prebuffer wait timed out 10 times.
2009-01-22 09:20:19.368 NVP: Prebuffer wait timed out 10 times.
2009-01-22 09:20:21.168 NVP: Prebuffer wait timed out 10 times.
2009-01-22 09:20:22.968 NVP: Prebuffer wait timed out 10 times.
2009-01-22 09:20:24.768 NVP: Prebuffer wait timed out 10 times.

and it goes on forever.

The machine is connected to the backend via a gigabit link. At first I
thought it was the network connection, so I tried different cables,
different switch. Even changed computer and motherboard.. All of them
will show this behaviour sooner or later: LiveTV will freeze every few
hours.
Backend has 3 DVB-T card...
Watching LiveTV on the backend itself never showed any problems..

Running 0.21-fixes (SVN 19693, retrieved last Sunday)

What else could I do to identify the problem and fix it ?

Thanks
Jean-Yves
