Run a cable from the DTA output to the B input of the A/B splitter. Run a cable from the A/B splitter output to the TV. Now what you have is a direct line from the wall to the TV via the A side which carries unscrambled HD signals. And you have all the other channels which need descrambling via the B side. Set the A/B switch to A and then use the search for channels function on the TV to find the available signals. Using the B side you will use channel 3 and tune using the Comcast remote tuner. Obviously you will need to manually change from A to B side as desired.
I made a diagram of my current setup and the setup with the A/B switch. Before I go through all the cable changes, I think I am going to run the cable from the wall into the HDTV and scan for the channels and see if that gives me the channels. That should be the same as using the A side of the A/B switch in your setup.

Correct?

However, what I do not understand is since the signal coming out of the cable is scrambled how is the TV going to find the channels without a DTA box?
