We have a Series 2 / 140 Hour Single Tuner (ST). We just bought a closeout Series 2 / 80 Hour Dual Tuner (DT). We have replaced the subscription on the ST with the DT and it is working fine. What can we do with the ST without adding another subscription? I did not see any posts on removing the 140 Drive from the ST (it has lots of stuff on it which I know we can continue watching) and using it as a second drive in the DT. Does this make sense? Would the recorded stuff still be viewable? The ST is still running as it has not run out of schedule yet. Also they are both in the same room and are both responding to the remote... not a critical problem (so far) but? Thanks in advance.
