Ahh, just learned that now, but testing it with a ZDF recording leads to
restarts every minute. Checking femon on #2 showed the upper stroke at 65% 
(slightly in yellow area), the lower at about 82%, but Video/Audio rates 
were zero. 

Funny, I started the recording while femon was active on #2, thus vdr
took #1 for the recording, and this succeeded (001.vdr). Stopped femon,
stopped and restarted the recording via vdradmin, vdr took #2 for the 
recording as expected, and the restart loop got going again. Something is 
definitely wrong with #2. 

This is reflected in the recording dir and the log:

Did that, but unfortunately, it wasn't the reason :-(. But thanks for the
heads up - didn't notice before.

Will check #2 cabling tomorrow. Thanks, Udo.
