If you run Ubuntu on your desktop check out the "arista" transcoder. It has a default output for our beloved N770 and N8x0. It may also work for the N900 but I've no way of testing that. The results are excellent and look great on my N810. This is the most polished transcoder I've come across. It automatically recognizes all video devices and determine the input codec. It will even RIP from a commercial DVD if you've installed libdvdcss2.
