Hello, I have a question about my TIVO with directv. It might have already been answered but I couldn't find an answer. I recently got an HR10-250 Hughes DVR from eBay and I needed to see if I can use this unit using only one satellite cable connection instead of running 2 sets of cables from the dish for tuner 1 and tuner 2. Can this one line be split? Using a splitter so that I won't have to run a seperate cable in the room? Someone asked me about destackers and stackers which I have no idea what this is. Please help! Thanks..
