My opion is, that it is easier and more convient to use 2 lists:
One list for the user and one list for the computer.

The "uniq" number may be the MD5-hash of channel name, 
frequency, polariationm, orbit and PID etc. That should be "uniq" enough
and is easy to generate.
The "uniq number" is only required to search the channel data fast
enough for the timers and the zapping list, or?
So such a "hash value" may be a sufficient way to go?

The user can sort "his" zapping table as he likes.
VDR can sort and expand the computers list as required.
If a channel is renamed or moved the user will be warned,
that the chanel seems to have disappeared.
To make that more convinent a third list with the
"old chanels" may be use ful, but not requored.

The other way is that the timers stores all relevant information
for recording.
