I was watching a movie last night on a PPV channel.   I had hit skip back only once earlier in the program.  Then I noticed that the movie jumped live.  I thought strange so I skipped back but it was exactly at the point where the jump went forward.  So I skip froward and I go live.  Well I messed around a bit and every time I skipped back it would go back to that point in the movie where it jumped forward and skipping forward would always go live.  If I hit pause nothing would happen.  I had to end up reseting the receiver to clear the issue.
