Hi,
it looks pretty ugly, but it has "grown" with my vdr project and its 
easy to understand. BTW "cchannel" is a script to set the channel of the 
next recording as "CurrentChannel" in the setup.conf for the next time 
vdr starts. So if vdr ist started by nvram-wakeup it starts with the 
channel of the upcoming recording because I had sometimes problems with 
switching the channels.

Greets Helge.
