hi, so far the phone's been great (except for the part where i always have to swipe to unlock, and then swipe my code). but i have a couple of more noob questions: i was able to copy some songs from my itunes library(bought from itunes) to the phone with no problems. i was kinda surprised they played. i then tried to copy a movie to the phone (.m4v format) from my itunes library (not purchased from itunes). but for some reason the movie wont play (star trek). i get the error "cannot play video". any idea why i can't watch the movie? do i have to convert it? i simply downloaded the digital copy when i bought the bluray version. thanks in advance.
