Neverless I'll go with that for now ...

My current plan is to use the channels.conf file much like a frequency
table in analog TV.  xawtv's has tv station list with all that
meta-information like hotkeys.  That list just maintaines a reference
to the tuning information, i.e. something like "channel = E4" for the
analog tv (which the frequency table will map to a frequency).  For
DVB I just need a some ID (first column of channels.conf file?) I can
put into the tv station list and which I can use as reference to find
the tuning information.

Why?  repeating doesn't hurt much as the table is autogenerated anyway
(and small enougth that we don't have to care about the memory it
takes), and a flat structure is easier to handle ...
