Just add a call to

    cThread::EmergencyExit(true);

after the "read incomplete section..." error message in eit.c.

Yes, it would appear that the channel switching problem is now
the remaining big issue, after recording and replay works flawlessly.

I did activate the EPG scanner a while ago and replayed a recording.
During replay I noticed some picture disturbances every now and then.
Closer investigation showed that the disturbances occurred exactly
at the times the EPG scanner switched the channel on my other two cards.
After turning off the EPG scanner replay worked fine again.

Ralph: is it possible that there is some crossover effect, causing
replay disturbances on the first card when the channel is switched
on the second or third card? Or do you think this has to be a problem
in VDR itself?
