These two ports are for transcoding videos in a way such that the Sansa Fuze media players can play them.
fuzemux/pkg/DESCR: To create video files for the Sansa Fuze (without using the official the official "Sansa Media Converter", which is Windows-only, produces files with bad A/V sync, and is a bit annoying), the video has to be transcoded to mpeg-4 part 2 video and mp3 audio, with specific codec settings, frame rate, resolution etc. The purpose of fuzemux is therefore to remux avi files into the exact container format required for playing them on the Fuze.
