Movie Makers and DVD players

So, I want to make a video. I already made one but I`m having trouble trimming the clips. I use windows movie maker. I can`t seem to trim the clips to match the rythym of the song. It`s off by like 1 or 2 seconds. Does anyone know how I can fix this problem? Or can some reccomend some other video makers?

Ok, so another question I have is about region dvd players. I can`t seem to find a free region dvd player on the internet so I can play Ayu`s DVD`s. I have one but it expires in a few days so I have to delete it before I have to pay for it. Does anyone know where I can download a free region dvd player?
