If you didn't uninstall the old version of Flash then repair permissions, you should try that.
Install the most recent version of Flash here.
Adobe strongly advises repairing permissions after installing Flash.
Launch Disk Utility. (Applications/Utilities) Select MacintoshHD in the panel on the left, select the FirstAid tab. Click: Repair Disk Permissions. When it's finished from the Menu Bar, Quit Disk Utility and restart your Mac. If you see a long list of "messages" in the permissions window, it's ok. That can be ignored. As long as you see, "Permissions Repair Complete" when it's finished... you're done. Quit Disk Utility and *restart your Mac.*

Currently Being ModeratedJul 2, 2010 1:54 PM (in response to Carolyn Samit)Of course I tried that first. I don't think this is a flash issue. As I said before it seems to happen on non-flash video as well. Saw it with H264 compressed quicktime movies.
The videos play fine on the YouTube site. The problem occurs when I try and play embedded YouTube videos on a non-YouTube page in SAFARI 5.
The problem does not exist in FireFox.
Reinstalling flash was a waste of my precious time.2 x 2.8 Quad-core Xeon and others, Mac OS X (10.6)
Currently Being ModeratedJul 4, 2010 3:44 AM (in response to Dharma-mac)Had exact same problem - I got only audio from embedded videos, although they played fine on YouTube. I narrowed it down to the Flash Plugin which I had updated to the latest version (10.1 r53). I replaced this with the previous version (10.0 r42) and it is now working. Hope it stays that wayiMac, Mac OS X (10.5.7)
Currently Being ModeratedJul 4, 2010 3:32 PM (in response to Dharma-mac)I think that is the problem. As I said, 10.1.r53 doesn't work for me. Had to downgrade to get it to work. Appears that Flash and Safari are not playing well together with newer versions.iMac, Mac OS X (10.5.7)
Currently Being ModeratedAug 9, 2010 8:39 PM (in response to Dharma-mac)I have had the same problem for some time on my home computer. The pages work fine in Firefox and my computer at work.
I did the uninstall and a new install of Flash but no luck, the new Flash is 10.1.53.64.
I at one time signed up for the Youtube HTML5 beta do you think that could be part of the problem?Mac Pro 2.66 quad, Mac OS X (10.6.4)

I have the same problem, but with Firefox. Embedded YouTube videos don't play in non-YouTube web pages. I can click the link in the top of the video to be taken directly to YouTube, and I can watch the video there, but when I click the big Play button in the middle of the video window, I just get a black rectangle.
I tried uninstalling Flash player as suggested above, rebooted my machine, and reinstalled Flash player, but that did not fix the problem. This is a non-Flash player problem that Apple should look into. I have not tried this on other browsers to see if I have the same problem there or not, as I do not use other browsers besides Firefox. I would rather not have to use another browser just so that I can watch embedded YouTube videos. I would prefer if Apple (or another knowledgeable user) can post the solution to the problem. Thanks!
