Ups sorry,
There are two cases in the messages log after the records stops:

first case:

vdr will restart and restart

It seems, vdr can't store the data to disk in time.
But my IDE disk is in DMA mode and the cpu is
low on load.

My system:
P-III 700Mhz
128MB
80GB Maxtor (reiserfs for the video partition)
2 old DVB-s cards

Thanks a lot

Jörg
