One of my CableCARDs is DOA, and I'm getting a new one tomorrow. In the meantime, if I just take it out, will the box just work the way you would expect it to as a single-tuner unit? Right now it keeps trying to record on the tuner with the crap card, which is to say it's not recording anything. There are some hacks I can use to sort of correct for that, but they're kind of a pain in the butt. Thanks in advance. Can't find this particular needle in the haystack of threads on the cards.
