almost all new movies are copyright protected. so you simply cant run handbrake and be done. the movie has to be "...adjusted" first. something I dont think that can be openly discussed here.
I will say its very time consuming to roll your own dvd movies. up to an hour and a half (with a fast computer)to actually make the movie.
I wanted to point this out because getting a dvd player is only going to be part of it. you will also need VLC for the codecs to play dvd movies and there may be other issues I havent though of.
