playbook and youtube html5 trial

I'm using the html5 trial on youtube on my windows laptop

but youtube, playbook and html5 don't want to work

keeps insisting I use flash

strange

Did you try turning flash off? Have a link?

I had flash off

I posted a link to myself of a youtube html5 video

It reverted to wanting flash

humm

some videos will play html5, some insist on flash

I was just going to say some work with flash off and some don't. Tells me that not all videos are in both formats.

uploaders fault, not playbook or youtubes
