Just bought a liteon dvd recorder. I have shaw digital cable. What is the optimal way to hook it up? With my vcr, I was able to record analog channels and watch any other channel I wanted to. I could record digital channels but I had to watch the digital channel I was recording. Now, this dvd recorder doesn't seem to have an input channel. If I hook it up directly to my cable box, I can view all the channels but I won't be able to watch and record different analog channels at once. This post is getting retardedly confusing so if someone can just tell me how they connected their Digital cable box, dvd and tv, I would really appreciate it.
