On your tv with dvr, you can watch one show and tape another. On the other tvs, you can watch another live show but not something that is already taped. If you are going to have three HD tvs, I would really recommend two dvrs so you can actually tape more shows. It gets hard when two shows are on at same time and you don't want to watch either live but watch a third show. I guess we could go upstairs to other tv but not a perferred choice.
