No actually you "scan" for them continiously. Isn't there a way to just
look what other pids are on the transponder you currently tune into,
while still showing the channel you currently have? I think we are
already doing this with the EPG. And when we do nightly EPG scans, we
would also find almoust all new channels.

Well I would simply let them stay in that list, just mark them "old".
The user still can select them if he changes his mind, and we wouldn't
have to worry about 3 channel lists, but only 2.
