I have a Comcast DTA, so no, it only has an RF out. But to be honest, I
haven't noticed any difference at all in the picture from the DTA recorded
on channel 3 compared to the set top box which comes in by composite.
Anyway, my point is null because it wasn't clear that Mike was suggesting
it only as a temporary workaround until the setup screen gets fixed.
