A lot of 'official' videos do not have the mobile syndication checked so the mobile site won't play these videos. I'm talking mainly about music videos.

The wrapper for youtube's desktop site is flash and if I load the desktop version in the bb it will say you need flash. Is that the main difference between the mobile youtube and desktop version that the mobile one streams something other than a flash container format? Opera doesn't work and Bolt version of youtube is extremely shoddy quality.
