[mythtv-users] Black screen on one channel plus some other random comments

[David Meiser]

I was able to get mythtv up and running and I'm looking now to set up 
the recording, but the problem is that I got to a college where they 
rebroadcast Dish Network.  I've got a channel listing, and I can figure 
out the Dish Network broadcast channels.  But, what I need is either a) 
to get someone to add the college stations to the data source of MythTV 
on the server side, or b) figure out how to parse the channels of the 
dish network schedule and put it into the database on my local end.

Any recommendations?  Anyone had to do this before?

Peace,
DAVE
