Add conversions for .smv so my mp3 player can play the videos. I know that the more you add the more complex you get, but you do call it the all-in-one

my mp3 player plays .smv videos and it has been hard to find a converter that does that without and does other types as well. I don't want to have several coverters when 1 would be better, but there isn't 1 "all-in-one" yet that I have found.
