I like that you can convert from almost any format to another with ease! Also it's easy enough so anyone could use this software without knowing how everything works or what each button does (which is great!).
It also makes converting video files super quick compared other programs out there which are much harder than using WUUC. There really isn't anything bad about wuuc at all but if i had one thing in mind then maybe adding an option of not having subtitles would be nice? But overall its still my favorite converter because most others have too complicated menus while being hard to understand when looking through them etc., So far nothing wrong here just wish they added some options where we don;t need subs though since thats pretty useless unless your trying to make something else into subbed content :).
