New HDPVR DCX3510-M. Recorded several program in different time however there's some recorded programs unable to play back. Tried to Play or FF but kicks back to beginning after a few minutes (screen all black out when play or FF). Also the "skip" buttom doesn't work on these programs. The start time indicated for these recorded programs are not the correct start time (start time is earlier than the correct one), but end time is correct.
