When this happens no output is read from the device, and myth locks up in the way you described (there appears to be a problem that the frontend can't easily spot when it has stopped receiving data completely and hence can't avoid locking up)
That turned out to be a good idea.

Dvbstream reads maybe 10k or so records and then returns an error 
"resource unavailable" (-1). There was no error checking on the read. I 
used the -o option to send the output to /dev/null. The rtp output 
behaved the same way.

Xine continues to run flawlessly on the same stream and same driver.

I'm now comparing block sizes, open codes, .... Maybe time to poke 
around the linux-dvb list.
