I am not using your scripts at the moment, but wanted to add 2 comments:

I have PAL and I always convert audio to AC3, because my Toshiba DVD 
player requires some switching in the menu, if I want to hear MPEG 
audio. So, converting to AC3 should not be restricted to NTSC.

You don't need mpg123 or madplay for conversion of MPEG audio to AC3. 
This is how I convert with ffmpeg alone:
ffmpeg -y -i "$1.mp2" -acodec ac3 -ab 224 "$1.ac3"
