Hey guys,

My Realplayer has always been running well without any problem. But recently, after I upgraded the operating system of my laptop to Windows 8, the trouble of the player comes up. But it happens only once in a while. When I use the realplayer to play the downloaded videos, it often gets stuck. Anf if I click to fast forward to a later point, the audio does not synchronize with the image. But before upgrading the OS, this phenomenon never came up.

Any one can give me some suggestions?
