Scott, I wanted to also say that if you're a little leery about modifying the system registry let me assure you that it's a simple fix and the only reason you should consider backing up the registry is only in the case where you happened to delete a wrong key etc. My computer was having the same problem a while back where I wasn't able to view my Yahoo news videos either and when I implemented the fix I didn't even do a registry backup. There is no need to reboot the computer either. Just start watching!

From what I've gathered about the problem it seems to be on Yahoo's end and apparently they are well aware of it and trying to sort things out. Instead of waiting for them to drag their feet I decided to get instant results.

Best,
Mike
