Hmm... maybe VDR could "have a look" at the signals of *all* cards ?
Only if *all* signals are missing a driver failure would be the reason
most likely . And even if not, if *all* signals are missing, restarting
would not harm anyone. This of course applies only to VDR boxes with
more than one DVB card built into it. With only one card, restarting
still isn't the best choice on errorhandling but an acceptable (even the 
slowest possible) one...

I don't know, are the drivers still *that* buggy ?
