comment Where can I find the man page for the set command?
when in doubt, always do type COMMAND to see if you are using the command or a shell-builtin function. When it is a builtin, help COMMAND | pager will give you the help with a cool pager. :)

comment Is it preferred to avoid use of “exit” in bash scripts as much as possible?
actually, using exit would be a recommended practice. in the abs-guide, for example, most scripts ends with exit 0.

Yeah, if mplayer can't play the mp4, then the conversion won't work with this method. :/

And does the audiodump.wav plays? If it doesn't, mplayer couldn't play the video.mp4 file, and then you're really out of luck. Maybe the file you are trying to convert is corrupted, can you test the process with another file?

that's weird... it seems that lame couldn't convert the wav. try removing the >/dev/null 2>/dev/null from the code to see the error message.
