Ok, I'll stop blaming flash and either blame Apple or YouTube...
I went to http://www.youtube.com/html5 and found that I was part of the HTML5 trial for YouTube and that YouTube videos should be playing via HTML5 and not Flash.
I left the HTML5 trial so that the video were being played by nasty old Flash... Guess what, it works.
Videos are now playing normally using Flash.
My suggestion is go to http://www.youtube.com/html5 and see if you are part of the HTML5 trial also, if you are, leave the trial and see how you go.
Bruce, John, whomever, my wrinkles are these:
1. Neither Safari, Chrome nor Firefox play YouTube video on my mid-2009 Macbook Pro 3.06 GHz Core 2 Duo laptop w/8 gb RAM and running Mountain Lion 10.8.3 (nor, as it happens, in my iMac desktop). I desperately need YouTube videos for my classes
2. I most often get the empty black box in Safari; in Chrome or Firefox, I often get the "unable to play/Learn More" error dialog. The video seems to be triggered because the Pause symbol shows, but no video ensues
3. I have updated Flash until my eyes bleed; deleted it, reinstalled it, ad nauseum. No joy
4. My Safari is not in 32-bit mode
5. I have dumped Trash, cookies, everything. No joy
6. I was not in the HTML5 Trial, but I opted in, opted out, and shook it all about. No joy
7. I have deselected and selected hardware acceleration in Settings. No joy
I have no idea why none of these fine solutions, so successful for others (to my increasing dismay ...) are not effective for me.

Funny thing: starting this week, I was also UNABLE to watch YouTube videos. I could see the whole YouTube page(s) but I would just get a blackout video playback screen instead with no controls either. So I visited the above link as suggested while noticing I was NOT signed in the html5 try out program. So, I DID join the program and now I can watch the videos fine.
I am on a MacBook (2010), Snow Leopard 10.6.8, using Safari 5.19.
Im with DCR on this one...
I have tried, to no avail, getting flash content to work from every angle. It will load the player, but certain swf files that are used for interactive content are loading Ad Nauseum. Granted my issues are more with swf files and how they are being read "hit-and-miss" via Safari (and even Chrome), the same rules apply. I believe we have a trifecta of problems occuring: with the browsers treatment of flash, the latest flash update (as per late January), and with the programs creating this flash conent that I am using for educational purposes. I did have (some) success with other web browsers (IE, Opera, and Firefox - kinda), but here's my gripe:
- I tried working on the program that publishes the flash content, re-exporting, re-uploading, and re-connecting to the content. No bagel.
- I tried working with the browsers that display this content, adjusting settings, clearing data, restarting, on all 5 major browsers. No bagel.
- I even tried working with my computer's settings to see if there was anything interfering with the flash content remotely. No bagel.
Now here I am trying to contact all the developers of their respective software (Articulate, Adobe, Apple, Google, even our site admin YourMembership). Need to find this solution or at least a workaround before all the students using this educational material turn into an angry mob lol
So, any solutions yet?
