About 1 out of every 4 or 5 shows I record on my TiVo Premier will not completely transfer to my PC using TiVo Desktop 2.8.3. Shows are not specific to one network. They may transfer 10, 15, 20, or 25 minutes of a show and then stop transferring. If I try to transfer them again they stop at the same point. I've tried with both a wired and wireless connection and it did not make a difference. I've tried with my antivirus disabled and they still won't transfer completely. Anyone have any suggestions as to what might be causing this problem.
