The lists under
Favorites List -> Edit Settings give only one tiny hint (at 615) about which channels are "Big Ten Alternates". To find out the truth, I had to go to the Guide, make sure it's showing
All Channels or
Ch's I Get, navigate to the 600 range, press the left arrow to see the channel descriptions, and then repeatedly press the down arrow.
Here are the Big Ten channels I discovered, half of which are labeled DTV in order (someone
else might reasonably assume) to hide them:
Code:
610 BTNHD Big Ten Network HD
615 BTN Big Ten Alternate
615-1 DTV Big Ten Alternate HD
617 DTV Big Ten Alternate
617-1 DTV Big Ten Alternate HD
623 BTN Big Ten Alternate
623-1 DTV Big Ten Alternate HD
625 BTN Big Ten Alternate
625-1 DTV Big Ten Alternate HD
I believe the "-1" channels must be added to at least one of my Custom lists (along with 610) so that the Guide can show what HD games are coming up. (However, I understand that all "-1" channels may someday disappear!)
It shouldn't be that hard!
