Frankly, I like it the way it is right now.

If you put all the information from the channel list into the timer,
then what if you modify a channel? Then again you would have to
transfer information from one place to another.

Information should be stored in as few places as possible (ideally
only in one single place), so I believe programming a timer with
a pointer (i.e. the channel number) to the channel is the right way
to go.

The channel and timer lists _are_ related, and VDR takes care of
any changes you make to them. If you make the changes outside VDR,
you'll have to manually make sure both lists are in sync again.
