STOP!!!! LOL....If you only get them for the movies....why not get two things:
WD TV Live Media Hub:

As soon as the 1TB is used up (30 - 40 movies or so) get yourself the 3TB WD MyBook Essential:

I have about 160 movies right now....all blu-ray. All rented via Blockbuster store/Blockbuster mail. I do the 3 disc at one time option then exchange in store. Also, Sundays is .49 cent rentals....I get six movies at a time
The process:
1) Use AnyDVD HD to rip disk to HD (I am sure many can find this one on torrent...i did paid version)
2) Use BDInfo (free program) to find where movie stream is
3) Use txMuxer to extract the video and audio stream into a .m2ts file
4) Use txMuxer to extract any forced subs
5) Use BdSup2Sub (free program) to convert subs to format the WD likes.
I can do 6 movies in about 4 - 5hrs (step #1 takes the longest as most computer BD drives are still about 10 - 12x read speed)
This is what your screen will look like if you get it:
