I have cable, and so have no experience with a digital converter, but I have enough experience with the rest of it that I should be able to help you through it.

If this was regular cable TV, you could run the cable into the splitter, run those signals into the LR and BR televisions converters, and it would work.

I'm IMAGINING that you could do that with a digital converter as well. You certainly won't harm anything, so it's worth a shot.

The only reason it may not work is if the frequency that the signal travels on is outside the frequency range printed on the splitter. I don't know the frequency range that the digital box uses, so I can't answer that question.

What's happening in your case now is that the digital tuner can only tune in one channel at a time, and THAT is the signal you're splitting -- just that one channel. Your ONLY choice is to split it before the boxes. Hope this helps.

Thanks for the suggestion. Will give it a try. It's worth it.
