Jet Black, I got this from the i-Tunes help menu. Most of it will be irrelevant in terms of talking about the store and the websites but it could be that some of the files you have downloaded originally came from a similar site and has parameters / rules in them which prevents you from playing them in the apps you have tried to far. It could be a player specific to where the original files came from. Such is the nature of sharing files on p2p.
