embedded youtube video not playing?

hi all

I've been busy learning Camtasia and editing and all that since xmas. I love it!

But, I've got a private you tube channel and an open one and a Vimeo Pro account (Got Amazon S3 too but found that a little challenging and VP was recommended by a big marketer)

And, the private videos looked soooo much nicer in Voo player than without so have loaded them that way for the actual landing page for a free WSO I'm putting together.

They wont play unless I'm logged onto Youtube. Weird. They have the message that they cannot be played in the frame.

But they do work if I'm logged on.

So is it Voo player, me or what?

PS - I also have Easy Video Player but havent installed yet and checked the thread - seems there are lots of problems so I was reluctant to start using that when I've got to get this launched - I've been fiddling and procrastinating for toooooo long and cannot give myself anymore reasons to delay except tech issues like this are kinda dictating that

Thanks for any tips
