And of course.. a PNR doesn't tell the user too much. Since the beginning 
of TV-Sets and VCRs the channels are stored by numbers and people 
normally memorize them very well. It's been since years now that "Das 
Erste" is 1, ZDF is 2, ProSieben is 7 and so on. I don't like the idea to 
look at a timers-list and having to guess what channel "12040" is.

Well but then... channel names can change as well. For example "tm3" will 
be (I'm not sure at the moment) "9 Live" in the near future. No matter 
what you use... if you change things without the knowledge of VDR, there 
will always be a way that you can break the references. IMHO this is a 
waste of time.
