But this is a different problem. Looks like VDR does an EPG scan.

Just have a look into your syslog for a line like this (in english):

	Nov 14 00:06:31 video vdr[31630]: info: Beginne mit EPG-Scan

You may also set EPG timeout to 0 to disable automatic EPG scans. You'll 
see a similar behaviour if you start an EPG scan manually.
