Can you simply fast forward / drag the scroll bar back to where you were? It would suck to watch 2 hours of a PPV, have to run out to do something else, comeback later (or the next day) and sit through the same dame 2 hours again.
FWIW, I think some of the Olympics replay streaming was like that - no obvious scroll bar to drag / skip forward.
You can scroll forward and back but the problem is there is no image when you are doing this like say when you are using the HBO GO app. Its kind of frustrating. I was watching WM 3 and scrolling forward and just guessing when to stop. This was while using Apple. But when I put it on Barely Legal on my PS3 it had chapters and everything. It was perfect. Each bookmark was a match and you could just use the controller to go to right to the particular matches you want to see. Then I put on Starrcade 86 on PS3 and it had no bookmarks. So I think its only on some and not all. My PS3 will barely do anything. Its been awful. Apple has been great loading and very minor buffering issues so far.
