I set "My Channels" as the channels that I am actually subscribed to.
I set "Favorites" as the HD version of any channel and and SD channels which don't have an HD counterpart.
I wish there two 1 or 2 more custom lists that could be created though.
Roamio Pro, wired ethernet
Mini using MOCA (from the Pro)
on Cablevision Raritan Valley system (Central NJ)
w/ Cisco PKM803 CableCARD on firmware 126.96.36.1991
