My sansa works fine, and works beautifully with ogg and mp3. But there is something wrong. SanDisk supports Linux, although, no software has been created for it, so I cannot watch videos on my fuze. Luckily, a piece of software written in python, has emerged that converts any video format into the sansa format. It works nice. But would it be too much to ask for an offically made converter on Linux, or Mac for that matter? Also, rockbox works good too. Thanks subversion!
