Anything ffmpeg is a moving target but..

You don't need to specify "-r pal" with "-target pal-dvd".
Note that any "-r" before input filename could have bad consequences.

"-acodec ac3"  --> "-c:a ac3"  or "-c:a:{stream} ac3"
This notation (is meant to) allow specify the input stream by number or
id..stream specifiers/index/type.
This could eliminate the mess created by "-map".

I think "-b:a:{ac3}" can only be 448k or 640k.
