I would also recommend making sure your video driver is up to date. Finally, do you notice any difference if you disable hardware acceleration?
None of those suggestions worked, I am still getting stutter.
Like I said in my original report if I play the same video with Internet Explorer it is perfect it does drop frames but the replay is flawless.
My view is that it has something to do with the way the latest version of Flash/Firefox gathers the 1.7meg data packages that the YouTube sends and re-assembles as a video that is going wrong.
The same thing happens with video's from DailyMotion etc
Anything happening problem still there and I am not alone, have a look at this Mozilla Forum link.
I have just done 2 screen prints from a YouTube video information, one playing back with Flash which stutters and drops frames and the other playback with Flash disabled..
Can't add screen print so have typed in the information as follows.

I have said before the stutter comes from the way Flash is sent in chunks and re-assembled as a video that is causing the problem. If you allow the video to play all the way stuttering, then drag the slider bar back to the begining it will play flawlessly as the downloaded chunks must be saved in a temp file.
Please do something, this is a well known problem.
Hello is anybody there?
Stutter still happening, why can't you fix it?
