How are you calling these commands? Looks like its being called from 
within mythtv somehow with the variables filled in.

The existing sample video clip that came with my ZEN is 128x128 15 fps 
with adpcm:stereo sound. Not sure if thats the only settings that will 
work but will start out modifying your settings to duplicate the sample 
video and will go from there. (Not sure about the 15 fps but it was 
Japanese language and was probably based on 50hz  pal originally.)

Thanks for the info.
