PS3 Media Server streaming .m4v

So I have the PS media server installed, and have been having a really hard time getting everything set up. Their forum kinda goes over my head, but after about an hour, I was able to get some .mkv files playing without stutter, which required me getting MKVtools to turn off header removal compression, but I still can not manage to get an iTunes Library .m4v movie to play. I get the data is corrupted thing. Tried just about everything on the forum I could find, but no one seemed to have a lot of problems playing these except when they are ripping their own copies from handbrake or something like that. These are paid for and downloaded digital copies. I have replaced the mencoder with the 1.40 version, which made the PS3 take about 30 seconds to decide the data was corrupted instead of the 10 it was before, tried to force transcoding, and I am out of ideas. Please help...
