I've had a 970A for quite a while. Although it has problems occasionally re picture breaking up, signal loss, etc. on certain channels, ,that is not what I'm concerned about now. A couple of times, including a few days ago, when I've had two items programmed, one on one channel at 8 pm, and another on a different channel for 9 pm, the 8 pm one worked just fine at 8 pm, and then 5 minutes later, at 8:05 pm it switched to the 9 pm channel. Luckily, I was right there, caught it doing that, and tuned back to the 8 pm channel. When I looked later, it had turned the 9 pm timer to off, but I had definitely programmed it correctly. Makes it risky to trust that it can do more than one item in a row.
