Obviously, you didn't read my answer to your question from
a few days ago, so at the risk of looking selfish for 20 easy
points, let me basically repeat what I wrote then:
If your YouTube looks stuck, and you get advice from people
to update, change or install things:....DON'T. It's never good
to fool around with things you may not be comfortable with
or knowledgeable about -- such as java scripts, flash players,
firewall settings, antivirus utilities, pop-up blockers, registries,
or even different browsers. Absolutely none of those things
are going to help you, because your computer/YouTube was
working perfectly fine before, right?
The first and best option should ALWAYS be to try and work
with what you already have -- rather than disabling, erasing,
separating, uninstalling, altering, downloading, installing, or
changing things (which will make things worse for you).
Whenever YouTube seems stuck or displays strange things,
empty your cache of all "temporary internet files", "cookies"
and "history". Things will be okay afterwards.
If you're not exactly sure how to do this, or if you want extra
tips on how to make YouTube run even faster (all without
having to install, buy or change anything), click on my avatar
and email me. I will lead you through "cache" clearing and
my other tips using easy and understandable "baby steps".
[Note: a big source of problems is Google Web Accelerator.
If you have it, dump it, burn it, trash it, disable it, get rid of it,
uninstall it -- do whatever you can to get as far away from it
as possible (even though this contradicts my own advice).
You can also forget trying "Don't Accelerate this Website".]
