I did a scan with the intent of typing in all the channels I found. There are too many for me to do that. Bottom line is that it seems to be the Broadcast Basic channels, with HD channels in HD and duplicated in SD.
I didn't see any Family Cable (iO Value) channels.
There are also two ANALOG channels, 17 and 119, showing spectrum analyzers.
IM Sent. Takes time to do so but that's what I did with my list.
Unfortuantely when I did my weekly QAM scan back on 12/4/2012, most of the extra channels I IM'ed you are gone along with TCM-HD which was was I was getting before all those extras popped up.
