i remember reading that the ps3 has similar properties to itunes, itunes lets you use your account on 6 different computers which lets you download the songs which are protected files and if you play them on the other computers that you have signed into you can play them there, since i read that i thought that the features been there for a while.
sorry to start cluttering up, but i couldnt see any "edit" button to change my origonal post
if you could merge this post to my first one that would be good, i just couldnt seem to do it myself
UPDATE - turned ps3 on this morning and it started up and everything was fine, didnt have time to see if games worked or anything but i would put money on the fact that they work.
