Have you considered TVersity (http://tversity.com/)? Its similar to Orb & has full N800 support. I tried it with my N800, after TVersity came out with N800 support in beta. Overall I was happy with it, but did not keep it in the end - due to my underpowered PVR being unable to transcode the video on the fly. But I would say, if your PC is up to the task, then maybe you should have a look at this app, if you have not yet done so.
