It's not a bug - it's a feature.

The problem is that sometimes the driver just doesn't deliver data when
VDR wants to start recording, and the only way (so far) to reliably recover
from that is to reload the driver and restart VDR.

You can disable this feature by commenting out the "EmergencyExit" call in
the section

      if (time(NULL) - t > MAXBROKENTIMEOUT) {
         esyslog(LOG_ERR, "ERROR: video data stream broken");
         cThread::EmergencyExit(true);
         t = time(NULL);
         }

in VDR/dvbapi.c (line 553 in the original source).
VDR will then just rely on the driver to deliver data. However, I don't
know whether it will work if there is an encrypted transmission (which can't
be received due to the lack of decryption hardware) followed by an FTA transmission
which shall be recorded, and the recording starts while the encrypted one is
still going on.
