normally one can redirect the output of VDR to a logfile, but it does not seem to work with the runvdr on Linuxmce.
I tried changing the ">/dev/null" to ">/tmp/vdr.log" in runvdr but that only gave me an empty file. also giving VDR "-v 3" did not help. Is that somehow disabled ?
That would help me alot trying to find out why VDR is not working. At the moment I can only guess
Try tail -f /var/log/messages in a Konsole session...
Then use /etc/init.d/vdr start in another Konsole session and watch the messages log to see whats happening.
