don't upgrade the firmware mate otherwise your fucked lol
most of the new games just take a while to crack thats all so just wait until they are,

do a search for a media convertor or something like that and it will change what you need to mp4 (i think i can't honestly remember now??)

all you do is put the movies in the movie folder you create on the memory card with your conversion programe
this is an old link but it explains it better plus there are a lot better methods now so just have a read to get the basics i guess
