I don't think it is even remotly possible as the iPod Nano is lacking the chipset needed to play videos. If anyone cares to enlighten me on the topic please do.
I have never tried, nor do I encourage the use of iPodlinux, but it has been brought to my attention it maybe is possible. So feel free to look and give it a go. http://ipodlinux.org/Main_Page
Yeah it all depens on what you think is most important, and for some just a great music player isnt enough.
I asked for a friend cause he wanted to do it but he gave up affraid it would mess up his nano thanks a lot for the replys
