Sadly, the PNR isn't unique in general.  It is possibly true at 19E, but not 
at other positions

For example, on Hotbird, both TPS's "Cinestar 1" at 10758v and OTE's "Extreme 
Sports Channel" at 12188v use PNR "1201".

Another, much more common problem is where transponders number their channels 
"1,2,3 etc".  This happens on Hotbird, and much more at other positions.

My suggestion for a solution would be to use the channel name as the unique 
identifier.  

A compromise, would be to store the channel name with the timer information.  
Whenever VDR starts, it could then cross-reference the channel names and line 
numbers in the timers with the current channels.conf and make the necessary 
corrections - or at least warn the user of the problem and delete the 
offending timers.

I expect that this PNR problem will affect the EPG data in VDR as well.

Regards,

Dave.
