#version 1.1
#Changes 1-1.1
#Added aspect ratio. There will be black bars on top and bottom to keep the resolution at 320x240 to avoid software scaling on the Z.
#Fixed AV_DELAY
#This script should convert any mplayer playable video file (audio + video) to ogm format playable on the sharp zaurus 5600 using mplayer with Tremor codec support. You need mencoder and mplayer of course, plus oggenc and ogmmerge.
