Hello I have a question that I hope someone can help me with. I just signed up for HDTV service through Direct TV. There is one cable wire that comes into the bedroom, which is split into the office. The way we have it set up currently is 1 receiver for both the bedroom and the office, so the same channel is displayed in both rooms simultaneously. The office tv is HD, but the bedroom tv is not. With the new HD service, can I still split the cable to the two rooms with one receiver?
