We have a standard definition Directv DVR that we were told by Best Buy would work with only one satellite line even though the receiver is capable of accepting 2. If we put the line in Sat 1, the receiver constantly searches for Sat 2. While it is searching, if we move the line to Sat 2, the receiver shows channels fine, but won't record. I have no way of running a second line to this room location. Is there any way to either split the 1 line and connect both Sat 1 and Sat 2 with it, or simply get the reveiver to work and record with 1 line in?
