Yes ;o)) 100% sure in case of the 1.1.17. I don't know what
you have changed since then, but if I watch a movie on one
card and the EPG scan kicks in my tech patch nicely shows
the signal strength for each channel scan and as soon as
VDR reaches non available channel, signal strength goes
down to almost zero and the logs show "panic can't sync on
channel "xyz". Sooner or later VDR restarts. Same thing goes
for watching a (already finished) recording. AFAIR the same
thing happend in the 1.1.28 version (last version I had time
to play with)

Sorry, I never investigated the true code call that actually causes
this problem I just reconneted the antenna after VDR restarted
3 times in a row ;o))

Much easier: Just switching off the EPG scan in the setup does
the trick ;o))
