mmd10,
First, hello and welcome!
Second, have you upgraded your PE to Ermine? Also, have you installed the version of Adobe Flash that works? (I'll find the link for you if you need it.) Not that I'm convinced it helps much . . . .
The "Tube" app that came with the PE works just fine for me. "TV.com" also works. I don't worry much about videos on websites, but you should be able to at least get these 2 apps to work.
