Comment 5 for bug 1205735

There's a better solution than nemo-media-columns described at http://forums.linuxmint.com/viewtopic.php?f=208&t=136592, which is to use mediainfo-gui. Unfortunately you have to manually configure it, but on the plus side it does give you more info than the audio tab in nautilus.

Note that the original code posted to put in the /home/<username>/.local/share/nemo/actions/mediainfo.nemo_action file has an error in the Exec line and should be instead:

[Nemo Action]
Name=Media properties
Comment=Media properties
Exec=mediainfo-gui "%F"
Icon-Name=mediainfo
Selection=S
Extensions=mp3;avi;flv;webm;mp4;mkv;
