Through replay itself, you can record 1 show and playback a recorded show
simultaneously.
Outside your replay you can do what you want. Split the signal before it
reaches replay. If you use Replay's internal tuner, your TV and cable box
operate just like Replay wasn't attached meaning you can watch anything
you want and Replay will record on its own off to the side.
If your Replay uses the cable box, then the cable box will be tuned to
whatever Replay is recording, but you can still watch what you want using
the TV tuner, or if your cable box has 2 tuners, you can still use the cable
box while replay is recording.
