[vdr] Unknown VDR restarts during playback activities on NFS mount

["Buehl, Reiner (HP Services EMEA)" <reiner.buehl@hp.com>]

Hello,

during playback activities like fast forward, moving of marks and jumps
VDR restarts very often. This happens only on a system where the /video
directory is mounted via NFS. On the NFS server systems, the same 
recordings show no problems. On the NFS client I get the following 
messages in the logfile:

I use VDR 1.2.6 and dvb kernel drivers from CVS version Oct 23 2004 with kernel 
2.6.8.1.

Is this problem related to the NFS mount? If so, do I need to use
different NFS mount options? Currently I use defaults,rw,soft,nolock,noatime
as mount options. The general network bandwith (100MBit) itself should not be 
the problem...

Or is this a dvb driver problem?

Best regards,
Reiner.
