older macbook pro, runs great, internet *screams*, but what's up with youtube???

for a long time, videos there just don't load.

i may get a few seconds of the beginning sometimes but i mostly get a lot of frustration.

i'm running 10.5.8, fully updated.

safari is my browser of choice...i'm using no extensions at all.

used adobe tool to remove flash, reinstalled flash, repaired permissions, etc....did this a few times and no results.

java is up to date.

all cookies and caches have been cleaned.

tried chrome, no results.

tried foxfire, no results.

what's up ya think?

other video on the internet is perfectly fine, and pages load like turning a magazine page.

thanks in advance for any help at all!!!

cheers.
