I'll join once I figure out my new gopro. I'm still trying to figure out whether my attempt at the firmware update worked or not.
Tsquared - I just removed the firmware update from my GoPro (HD2) because it was causing the camera to freeze in record position and no amount of pressing buttons would turn it off. You have to remove camera from the case then remove the battery to stop it. It has been widely complained about in the gopro forums for some time now and it affects the new HD 3 too. seems Gopro have not been able to fix it. Some short trips were fine but most times it would misbehave and freeze up. Removing the firmware update fixed that issue. By removing the update I removed some of the features like remote control and some POV adjustments.
Heres something about the firmware upgrade issue and a link to the fix (firmware downgrade) if you need it http://www.youtube.com/watch?v=wOlypDzjkuk
Quite a few people returned their gopro but many, like me, who bought the HD2 were out of warranty period when the firmware update was done.
I hope you have one of the good ones and don't experience the issue. It Does take very good quality video.
