MediaPlayer Instancing..

Im creating a DLL, which is going to sit in the application for users to call functions from. Now this dll contains a media player instance, and the dll is set to persist, so within reason the dll should always be open and keep all the data it uses. Which Ive got working, however, I cant reference across to a form when using a class, and I cant seem to create a global mediaplayer object within my class.. Does anyone know how to make one, or if theres another way to do this?

Cheers in advance,
Tony.
