I think I posted in the history of this thread somewhere about how to get autocomplete to work.
Can you let me know.. are you using the stock youtube application or an addon?
The stock one played video in amazing quality, every other one I have tried to install doesn't look so good.
I was playing this video youtube.. "rise and fall trailer"
Rise and Fall Online
It should play super sharp. My HTC used to look way better than the iphone video, now it is on par.. not so good, muddy.
