VLC is very basic and all you do is press play, and half the time u dont even have to do that, it opens and plays automatically......

WMP, I personally dont like it and I dont use it much.....

Sonic doesn't burn downloaded movies.....

Nero, thats another story, I have never tried it, but I hear its good
I use dvd santa, its a very basic program and does everthing for you.......
