I already have divx and xvid working on the system, so that's not what I'm trying to do. What I want is for the movie file to appear under itunes under, for instance, the "TV Shows" category. So basically tag an AVI file as a TV show so that when I'm using Front Row I can see the name of the file from the GUI under TV Shows. I know how to put them under Movies (just put in movie directory) but there's no equivilent for TV Shows.
On the same note, I have a lot of vid clips within iPhoto as part of my albums. How can I get them to appear under "Movies" in Frontrow without making a duplicate copy in the Movies folder? I tried making a smart folder that rounds up all the clips in the Movie folder, but that didn't work.
