I have not found a site yet that does not work, but Hulu is an example of one that works poorly.

Most standard def Flash content plays smoothly full screen or embedded. Now, it would be nice to have a Flash player to play linked files like the Youtube app Android has. This should free up resources. They play great on Android, so should be better on the N900.

A Flashplayer to link to flv content for all- not just Youtube content would be sweet. Coreplayer has the ability to link to Flash sites and works passably for some content on my Tmo Dash.

BTW, Flash 9.4 on the N900 does use hardware acceleration. the option to leave ti on or turn it off is in the browser when playing content. I saw some posts in other threads asserting it does not.
