Is read quite a bit about the YouTube audio sync problems on both the HTC app and browser version. Sure enough when I got my desire I had same problem. On the HTC app you had to scrub forward a little them back again and it would then sync up. The browser version however wouldn't. But, since installing leedroids Froyo everything has been perfect. Wanted to add a happy story to the forum as all I see are problems, mines perfect and I love it.
