Hi guys, I dont know if its my browser issue but from 2:54 video image is frozen, the audio keeps running.
Downloading the video works well just in case!
Cheers.
I have found that after you start a video, allow the loading bar at the bottom to fully load before trying to jump around in the video. I was experiencing the very same issue and this resolved it for me.
I'm using Chromium and it runs fine for me. Jump around at will. :)
If you don't want to run Chrome, you can find a build of Chromium here: http://chromium.woolyss.com/download/
i have this issue in Firefox at work it drives me mad. i've watched a load of vids but they never show full progress bars cos i need to download and watch them.
