OS2007HE doesn't play Orb video. It's player doesn't have Real Format Codec. You have to use 2006OS. I use it all the time and I love my 770. You just need to learn how to use it. And you don't really need to buy N800 or N810. 770 is good enough to play video and MP3 and a lot of other things, even watching TV and calling landlines over the internet.
