Probelm converting my Blu-ray discs to mp4

I've been trying to convert several of my blu-ray discs to mp4 to use with my Apple TVs. I've been using MakeMKV to rip the discs. The mkv files play fine in VLC but when I use Handbrake to convert them, the resulting mp4 file is unplayable. Any suggestions as to what could be going wrong?

FYI - I'm using a windows 7 machine with the above mentioned software to rip and convert the blu-ray discs.

Now why didn't I think of that. Thanks for that most helpful solution to the problem. /sarcasm

I'm using the Apple TV3 preset

VLC won't play it. There is no error messages or anything. VLC just sits there. I don't have any problems with doing regular DVDs. It just seems to be the blu-ray rips. The MKV file created by MakeMKV plays fine though in VLC. So I'm not sure what is happening in Handbrake with the conversion.
