I am getting the same problem

Ubuntu 8.10 32bit, Pretty much the same as the post above

A bit more information

It is not just white dots, it is also black dots. When you have video displaying bright colours or white, you see black dots, lines. Youtube seems to be the only one effected, I tried Metacafe, and Google Video, and both showed their own material fine. When watching Youtube from google video however, the pixels and artifacts returned. When opening up the downloaded youtube file found in the /tmp file, the video displayed fine (Played in VLC)
Some video seems to be worse than others, and some videos display no artifacts whatsoever. It is just a suspicion, but I think it perhaps might be on the aspect ratio being properly converted into youtube. What I mean is that the low quality, ripped content, and anything put onto the youtube haphazardly seemed to give off the most pixel artifacts. The sponsored videos however, or videos that received proper conversions (Such as being in a letterboxed widescreen vs being pan-scanned) tended to be near perfect.

I am not sure if that helps or not, but~
