We have 3 TWC boxes but only 2 are DVRs. Do I connect the Digital Adapter boxes to all 3 TVs or just the 1 TV that's not DVR? I'm lost and really need to know what to do before I mess something up. Thanks.
I believe that you would connect the each of the boxes to each TV. If you google the models of these boxes you should be able to come up with the manuals. In any case you can just try it. Won't harm anything.
