Sorry for the extremely long time between replies - I'm off list and didn't

your message until today.  :)

Cool!  That's closer to how a true satellite system would work, but it's 
certainly
a lot of work.  ;)  It would be pretty trivial to catch a moving channel if 
we had all
of the info available during a run.  I think the NIT-scanning stuff I have 
right now
would be a good start.  It could be gradually shifted over to being a 
definitive source
for channels if that's the way that we decide to go.

Does this offer still stand?  I could easily re-write my patch to remove the 
dvb_pid
table if you could provide this priority list stuff for me.
