TVersity - too many folders!?

I have a new desktop and I just discovered I can stream from my desktop to my PS3. Well, the program I am using to stream is 'TVersity' and when I go into my PS3 and go under 'Video' to play a movie I have multiple folders, some with files I don't even have that can't even play under names like '212$@!2sc". Is there anyway to just have like four folders titled 'Movies' 'Music', etc instead of all the folders like 'Tag' 'Hulu' etc that come on there already?
