You have the right idea, however it would probably be a -2 or -3 .a sub channel you mean something like 54-1???
the CW here is on channel 5 in my area
i never watch me tv
The -1 is the OTA version of the D* channel if your locals are on D*.
For example, for you KNBC is on your D* local channel line up ...
I don't know the channel number, but lets say its on D* on channel 4 ....
KNBC would be available to you OTA on 4.1 or 4-1 and the Me Tv would be on 4-2 (not saying thats the right channel numbers, but thats what you would see on the TV in the guide.)
