Related to the above, when tuning to an off-air channel (as discussed 
before, in the UK these usually switch to a data stream of some sort), 
you get stuck, as next time entering live tv will attempt to tune to the 
same channel (which is helpfully also saved in the database).  Ideally, 
some kind of no signal/no video message would be displayed and you'd 
just be able to browse to another channel.  I've no idea how difficult 
this would be to do though, so another solution might be the appropriate 
route.

I also have:

* seeking in LiveTV is broken.  (For me, DVB only).
* channel changing causes some kind of deadlock occasionally

For the latter, my previous patch vs the different method that you came 
up with appeared to work ok, although I can't say for certain as they 
weren't applied to the same SVN revisions, and plenty else has changed 
since then.  (I appreciate that my patch was technically wrong as it is 
waiting for the tune to fully complete).

Sorry I'm not making much progress with the above, I haven't really 
figured out what the code is doing yet.  I'm more than happy to help 
with testing etc until I manage to get up to speed though.

Thanks,

Mark
