@eric Just submitted another log for this and I'm uploading a video to youtube now, I'll edit the post to include it later.
After watching the first half of Monday night football I clicked back once, that seemed ok, clicked back again and it jumped back at least 30mins (this is when I started recording). Paused and moved back to live and the video doesn't play, press back and it starts to play again, press back again and it jumps back at least 30 mins, press FORWARD and it jumps BACK another 20-30mins.
Hopefully the video along with the log helps. I still haven't seen this behavior if live is less than 1hr.
