There is an object of cChannel for each channel, and they are stored in
a list. You can either patch VDR to modify cChannel::Name() so that it
takes the original name as an index into some database of yours, or
modify the names in your channels.conf and set "Setup/DVB/Update channels"
to "PIDs only".

Just curious: what's wrong with the original names?
