Please remove -q:a 0, test current FFmpeg git head and provide command line together with the complete, uncut console output. Also remove -maxrate, if it has an effect, it would be one that you didn't intend. Finally remove -preset veryslow, it has no effect afaict. Old MEncoder documentation suggests not to use -q:v 0 but instead to use -q:v 2.
