Converting Bluray rip to DVD format ?

Hello,

First of all I hope this is in the right section.

Second, I'm a total newbie when it comes to this stuff, it's all Greek to me.

What I'm trying to do is convert a Bluray rip (mp4 about 4gigs) to something I can fit on a DVD to watch.

I have DVD Flick and DVDFab. I tried converting it with DVDFab but the video was awful.

Any help would be great, thanks.
