what build (revision) of jpcsp are you using and where did you get it?, all the latest builds should be obtained from the buildbot found here (other sites are unsupported)
http://buildbot.orphis.net/jpcsp/
I'm not sure I understand the problem correctly you have the Media Engine option enabled but still get a fake mpeg screen?
Could you post the error message you are receiving or a screenshot (remember to scroll to the top first, if its a console error))
also have you tried to run as administrator?
