We haven't decided on a solution officially. I had posted my first suggetion after seeing diff between XawTV and tvtime frequency table lists. :) > At first I believed that a config file for frequency lists would be a > good idea.

I think the verbosity isn't bad temper for the open format. Even if verbose format is not welcomed, we can generate simpler file from it. It would be better to enable to combine multilple files into one file by a script. We can also generate it from XML, or to XML.

I'm very sorry I know only Japanese broad cast things. > Maybe this weekend when I get a chance to re-clean-up our frequency code > I'll post my suggestion for a header file solution.

It would be nice to add a "user friendly table name" for each file. For example, it would be better to display "Japanese broadcast" than "japanese-bcast" for TV applications with GUI. Of course, the later name is good to input from a keyboard for the user. Kentaro
