[mythtv-users] Channel changing on from mythtv ideas

[Matt]

I'd be willing to give the sniffing a shot.  If I had a Tivo or a 
motorola cable box :-)
Although, I would be interested for the cable box that I have.
However, is sniffing necessary?  Have you tried getting the information 
from the manufacturer?

Also, have you looked around on the net?  Perhaps someone has already 
done the work.
