pKlungness, I've merged your latest thread into this original one.

Compressing blu ray to fit dvds is going to lose some quality. There is no way around that. But the results can be quite good...you'll just have to watch the movie to see if you like the output. Going to DVD9, double layer dvds, will be much better obviously.
By the way, the normal output from BD Rebuilder is still blu ray video (AVCHD compliant). You would need a blu ray player to play them back, or play them on a drive in the computer using software that is capable of playing blu ray video. It is possible to use BD Rebuilder to output as dvd-video, but the results will be standard definition video and that reduces quality quite a bit.
