Youtube problems (time/video skipping)
In Youtube, if you go back in a video, the video will be so far behind, it goes incredibly fast (like 4x speed) for a couple of seconds. You can hear the sound and video not matching up for this time - sound is working as it should.
This is very annoying for me when I'm watching a in-game video and I need to pay particular attention at certain moments. This skipping bug makes it so that I have to start way before the actual stuff happens to have it in real time.
This does not happen in FireFox or Chrome, so I doubt it's the Flash player's fault.
Opera version 30 for Win 7 64-bit.
This doesn't always happen, but I'd say in 95 % of cases.
