The only advantage in operation that Comcast had over directtv that I know of was that you could find a show playing with the beginning in the buffer and that you could record that show and everything in the buffer would be saved too. In other words, if the time was 12:25 and the show started at 12, you could hit record and the show was saved from the beginning. If I had started to watch the show above at 12:15 from the beginning and I needed to leave, I could hit record and see the whole show. Unfortunately now that feature is gone. Now record only saves the show from the current time on and does NOT save what is in the buffer.
