Connect external hdd w/movies via usb to xbox/internet box for tv play

I have a lot of dvd in binders just taking up space and I am not very good at putting them away either. LOL I decided to rip them all to a hard drive. I want to know if there are devices out there that I can just connect the hard drive to via usb and play the movies? I know that I can use a Media Center Extender on my 360 but I didn't really want to keep all these movies on my pcs hard drive. I based that decision on the idea that if I am streaming a movie from my laptop, it would slow it down if I decided to use it while the movie was playing; plus I want to be able to play movies on other tvs besides just the one with the 360 connected to it. Thanks in advance for your help.
