The 516 channels listed for dvbscan are all tv channels, I already
discardeded radio channels and channels without names (listed as [xxxx]
in dvbscan). Dvbscan was run just a few minutes after mythtv scan, so
the results shuld be comparable; at least some of the missing channels
send 7x24.

Sorry about the chanid/channum mixup, should have been obvious. 

Tune/watch dvb now works as before. I should get a CAM within the next
few days, I can do some more testing w/ encrypted channels and multiple
audio feeds then.

For now, I see two main remaining issues with dvb usability:

First issue is that Mythtv doesn't handle low signal/encrypted/inactive
channels gracefully. If you hit a channel where the backend can't read
data from the capture card, the frontend freezes up and requires
fiddling with setup to change the default channel back to something
usable + restarting the backend.

The second issue I see is the flood of channels imported by the current
scanning scheme; Scan should find ~ 500 TV Channels. About 50 of these
are FTA channels in a language I actually understand, the rest are
encrypted and/or in a langage I don't speak.

What would be nice would be a filter for the scanner where you can tell
it: just accept programs that are 
 - FTA or
 - encrypted for a CAM that's currently plugged in and
 - have audio in one of my languages (enterd on the scan form)

That should get the list of imported channels down to something much
more managable and useful.

Thanks, Martin
