622 skip back problem

[Tugboat]

Lately I've been having problems using the skip back button while watching recorded programs. While I haven't timed it, skip back will move back about 10 seconds and skip forward will move forward about 30 seconds. More often than not now, the skip back will not go back, but instead, go forward. When it does go forward instead of back, it does so for about 10 seconds like it would if it were going back. I have stopped and restarted the recorded program, but it does help.

Has anyone else experienced this problem? It's to the point now that I have to use the rewind function to go back for most recordings.

Thanks
