There was a video for WP7 in channel9 and i think was in Learn section.
I had a bookmark on it but recently they changed in a new area all these WP7 videos.
The video was about 90 min and it was from a seminar. The speaker, i can't remember his name, he was European, maybe from Holland.
He intoduced WP7 and he also made some animation with Blend.
The sample program he did it was a DVD collection using BestBuy service
I'm desperate looking for this video
Is someone knows the link please reply here
