The solution to your problem could very well depend on which
version of "flash" you have installed.
While the video is in regular mode (not "full screen"), right-click
on the video itself. From the drop-down menu, click "Settings".
If you get 5 icons on the very bottom row, you might be in luck.
The first 2 icons should both show you a monitor. Click the one
that features a graphic on the bottom of its screen (usually the
first icon). You should thus get "Enable hardware acceleration".
Whatever the box shows you, click the opposite, and then click
on "Close". This seems to be the solution for quite a few people.
Although this advice seemingly contradicts Macromedia's own
website, you can always double-check for yourself. Here is the

If this does not work for you, and you have the useless Google
Web Accelerator, trash it -- it actually ruins your YouTube.
Also, stay away from YouTube's beta homepage and any stupid
utilities or downloaders that people here on Y!A may be shilling,
because their responses have absolutely nothing to do with your
question, and their products may actually worsen your problem.
Besides, what kind of boffo answer is [my paraphrase]: "Although
you can't access or watch videos properly, get this downloader."
If all else fails, you might have to go to your "control panel" and
tweak the colors of your "screen resolution" to "16-bit".
Whatever happens, I would very much appreciate it if you could
