hey, i have the same problem..and when i try opening hd videos ( iron man 2 trailer for example) it get reaaaly choppy like around 1 frame per second!try using mozilla though..the video is much better..but its still pixellated..hope some1 has a fix for this!!

wht do you expect with flash 9. its has no GPU support so its all software rendered.

wait for flash 10.1 which has gpu support



******1 trick is to wait for the video to fully load and run on full screen.

The problem is that we are likely to wait forever. PR1.2 has no flash 10 either, right?

or if u want to get the real real youtube experience download the hide user agent app from extras. youtube will no longer know ur using a microb browser and will give you hd quality videos.
however be prepared from choppy videos as n900 doesnt handle that much streaming so well.

edit. havent tried this after overclocking so maybe its not as bad.
