Just found out that I finally managed to watch facebook video on my Desire

Im using LauncherPro Plus "Friends" widget, the facebook video will be played in a browser; the Facebook app which comes with AuraxTSense will ask you to play facebook video by either using "Movies" or "Streaming Media Player", which both options do not work. 

None of those tricks works....haizzzzz...dunno wat to do ed.... suspect is hardware faulty ed... I downgraded to 2.1 still no difference.....take out battery put it back oso same.... the hardware like just dead....

720p video recording definitely need at least class 6 or above. but I just tested lowest resolution for video recording also hang.
I check the folder, there is video file created but 0 bytes. not sure what's the root cause
