Lance you will need a 4GB memory stick or more, you may be able to store 2 films on the stick, a very expensive way of keeping movies, you can buy RW DVD's quite cheap, or buy an external hardrive approx £40+ this can hold upto 1000 movies (depending on size), if your TV is newish with a usb port then the external drive could plug in and you can play movies.
Once you have downloaded the Torrent and need to play it back through a dvd player try downloading 'DVD Flick' and transferring the files ready to burn to dvd/stick/external hardrive.
