Don't know if you will find a good free one, but for $35 you can get magic dvd copier. It will compress the movies for you so that they will fit onto the the standard 4.7 gb blank discs. The $35 is well worth it when you consider that a new dvd costs $20. Between myself and my dad, we have probably copied 200+ movies using this program and overall it has been very good. Occasionally a movie won't work for some reason, but usually it's because it's the disc is scratched or there is some other problem with it.
