Actually consoles dont really have quality control, see Last Remnant X360 for example.
But, all Xboxs and all PS3s operate pretty much the same, with the same (or very very similar firmware) , hardware, etc. Your PC might have any number of things wrong with it. Your PC probably also has a lot of stuff running in the background.... hard for any game maker to take into consideration every single piece of hardware, driver version, and user-fuckup that a game might possibly encounter. Its not always an issue of game quality and QA.
Sorry you cant get your games to work on PC though, that is indeed a bummer.
