Chad,

I *did* set up Capture card with input from Tuner0. And I *did* set up 
Video sources to my cable company. And I *did* set up input connection 
(indeed option 4) to link this video source with the capture card. And I 
*looked* in Channel Editor after I ran myfilldatabase - everything looks 
OK. So, it all makes sense but doesn't move me too far :-( . I still 
don't understand the comment earlier about setting up channel 
numbers/frequencies. If anybody can elaborate, I would greatly appreciate!

That said, I noticed something that may be relevant to this problem. 
When I set up Input connection for my combination (Tuner 0 -> 
CableCompany) I set up the starting channel. As long as I don't start 
front end (that is, exit and start mythtvsetup) - the value stays. But 
as soon as I start (and then exit) frontend and then start setup - the 
value in the Starting channel field is gone.

Maybe it's related - maybe it's not. But either way I am very confused 
by references to channel numbers.

I did install MythTV several times on different computers (FC3 and FC4). 
I don't claim to be an expert by any means; but I think I checked the 
obvious places...

I humbly suspect that there is a bug, and I'd like to do my best to 
troubleshoot...
Thanks
Felix
