This is what I use as my Mime fix list:
# text/*
htm(l|) $SET(0=text/html)
js $SET(0=text/javascript)
css $SET(0=text/css)
# application/*
exe $SET(0=application/octet-stream)
zip $SET(0=application/zip)
rar $SET(0=application/x-rar-compressed)
pdf $SET(0=application/pdf)
swf $SET(0=application/x-shockwave-flash)
# image/*
jp(e|)g $SET(0=image/jpeg)
gif $SET(0=image/gif)
png $SET(0=image/png)
bmp $SET(0=image/bmp)
# video/*
avi $SET(0=video/msvideo)
asf $SET(0=video/x-ms-asf)
mp(e|)g $SET(0=video/mpeg)
mov $SET(0=video/quicktime)
# audio/*
mp3 $SET(0=audio/x-mpeg)
wav $SET(0=audio/x-wav)
mid $SET(0=audio/mid)
Note: I use Opera, and set that browser to strictly conform to MIME Types. This filter usually is deactivated, I only activate it when a server I'm on is notoriously bad at applying the correct MIME Types.
