Blu ray Conversion to ANY other Format?

Judging from my lack of results while searching for something to convert blu ray to some other format, I’m guessing there’s no easy way to do it, but is there some way to convert blu ray to some other format?  I’m mainly looking to be able to watch the movie in other rooms with only a DVD player.  I don’t want to have to use a hundred different programs to do it, no separate programs for the audio and all that.  Looking for something (relatively) simple.
