Have you tried *reducing* the buffer size in vdr?

At line 31 of dvbapi.c there is

#define VIDEOBUFSIZE (1024*1024)

You could reduce this all the way to 

#define VIDEOBUFSIZE (32*1024)


This way, vdr would make more but shorter I/O requests.
Maybe processing some of vdr's I/O requests takes so long that
in the meantime data from the DVB-S card are missed.

P.S.: I have upgraded from a PentiumPro150 to a Pentium III 450
system and I am no longer seeing any glitches.
