Is there a free way to remove DRM on iTunes protected m4v files?

I got a digital copy of a movie along with a blu-ray I purchased, and I downloaded it through iTunes. However, I want to put it on my LG Optimus S Android phone, and to do this I would need to remove the DRM. Here's the problem: Every converter I found is simply a trial and only allows 1-3 minutes of conversion, not the 1 hour 54 minutes I want. So, is there a freeware that works with the most recent version of iTunes and can remove the pesky DRM?
