Try:
edit dvbapi.h

At around line 58 (vdr-1.0.4) there is
#define VIDEOBUFSIZE  MEGABYTE(1)

Change it to
#define VIDEOBUFSIZE  MEGABYTE(10)

In my case it helped very much - I never had any "buffer usage 100%" 
restarts any more.

(take care: the 10 MB will be used for every vdr-thread - so if you have 
to less memory (less then 128 MB) it can become a problem  - then try 
videobufsize 5 MB or 2 MB)
