One of the annoying things about DVRs is that you can’t easily record a show if the program guide is wrong. I wanted to record a basketball game; but the guide showed a series of 30-minute programs in that time slot instead. So, I had to set the DVR to record a couple of them plus 2-hours extra time (which is the maximum) on the last one. There is no way to schedule a recording on a particular channel for a set amount of time. I like modern technology except when it doesn’t work well as things it replaced.
