Sometimes, I'm watching something I recorded on my DVR (Scientific Atlanta), and I stop in the middle of the show. When I try to pick up where I left off the next day, I find that the DVR has rewound the show to the beginning, and I have to fast forward to the right spot. (This doesn't happen all of the time.) I realize that this isn't a huge problem, but its mildly irritating nonetheless. Is there anything I can do about this?
