Great, so this is already in place. Then only the occurences of 
fatal exits need to be checked and evaluated if they should be 
really fatal or if vdr could still run.

Yes, and just log the offending line(s).

If no channels can be read I would consider it fatal. If at least one 
good entry is there, it is not fatal, so VDR should start.
