Kaffeine channels lost. New ones found but not all.

I rescanned my channels in Kaffeine. I found 4 new channels which I assume is a result of the new digital situation. They are just crappy PBS stations. I deleted my old list but when I rescan, the old channels are not refound even though they are still broadcasting. Whats up with that?

Does anyone know if we can expect any really good changes after the official conversion? So far I am not impressed with the digital braodcast lineup. All the extra channels such as #.2 and #.3 just show the same reruns over and over and over. Not even any real programming. Just a bunch of community discusssion crap.
