So I have some files (p90x not porn

) I want to burn to a disc that are too big to fit on one disc each. I tried using windows movie maker to cut out parts to make it fit, but after burning it to a cd it doesnt work on my dvd player, my version of nero apparently doesnt have an edit video section either. Is there any free program that I could either
A. cut the vids in half or B. compress the file to fit
thanks!
