Hey guys, First post I know but i've searched the web for an answer and can't find one. For the last few weeks Youtube just stops buffering after around 30 seconds and the slide bar at the bottom of the vid goes back to 0:00. The page or Mac are not frozen, it just needs a refresh to continue watching the Vid. I'm using Safari, I have a iMac 2.7 GHZ I5, 4GB using Lion 10.7.4 Its 16MB fibre optic, ethernet connected I've reset Safari, emptied the cache and updated the newest version of flash! Can't really think what else to do! Any input would be appreciated!
