Something happened on my Debian system as it no longer knows to use "Movie Player" AKA "Totem" to open all .wmv, .mpeg, .mpg, .avi, etc etc etc files.
When I try and open any media by clicking on the URL, Firefox has no clue what to do with it & I get this
ERROR.
If I save it to my PC, I have to always tell Linux to use "Movie Player" to open the file with over and over for every file. What happened? Why did my system forget to use Movie / Totem Player?
