How do I record one progam while watching another one at the same time with satellite TV? Do I need a splitter or something? I had no problem doing this with just an antenna; but now that I got satellite TV, I can't seem to do it anymore. I really need to be able to do this, and soon. Even though I don't think it matters, I have Dishnetwork. I am not a technophile, so please keep it simple.
