BlueRay file to MP4 file

I created a file from a BlueRay disk (used DVDFAB) for archive. I now want to create a MP4 file to play on my Western Didital TV HD but for the life of me can not figure out the magic sequences with DVDfab (file to mobile). Can someone shed some light on the proper process, I have tries several combination in generic.

Thanks
