I have exactly the same problem, reinstalling Flash and Java did NOT help.
Have no idea what to do besides reinstalling Safari 6.01 if that is possible....
(After some problems I was able to download Safari 6.02 via Software update)
Running 10.8.2 on 2008 MacPro

Same here, some videos simply do not load at all and I get a blank screen.
I actually installed the update via software update, no fancy .pkg downloading involved.

1.Are Plug-ins Enabled?
Safari > Preferences > Security
Check the box for Enable Plug-ins.
2. Check whether you are currently in YouTube HTML 5 trial.
At the bottom left of the page uncheck the box for
"You are currently in the HTML5 trial".

Sorry, I completely forgot to post an update.
The way to fix this is actually to reset Safari, as per this thread
Thanks for your help!

I had the same problem. I already had plug-ins enabled, so that didn't help. But removing myself from the YouTube HTML5 trial per dominic23's suggestion 2 was sufficient to get things working again. It appears there's a problem either with Safari's HTML5 support or YouTube's use of HTML5. It's possible the Safari reset clears something YouTube is looking for to know to ship you HTML5 instead of Flash, and that's why a reset works, but that's pure speculation; it's possible the reset works for entirely different reasons.

In my case this was not about HTML5 being enabled on youtube. I was using Flash and some videos wouldn't load. So the transition to 6.0.2 messed something up that was solved with a Reset.
So you milage may vary, but there's certainly more than just HTML5 to this issue.
