Are the DVR's and the satellite boxes in the same unit now? I have a DVR that is not tivo and I used it with digital cable a fewyears ago (needed cable box). The sucky part was it could not reliably change the channel on the cable box since it was trying to mimic the remote, it had a gizmo you hung in front of the cable box that sent the remote signal. Going to a single digit channel was fine, on 2 digit channels it didn't seem to get the first digit most of the time.
