When I put my disc in it loads...then it displays

Wrong disc usually indicates a problem with the lens mechanism of the DVD player. It can be dust/lint blocking the path of the laser there by preventing it from reading the disc or it can be a mechanical problem like lens out of alignment. You can attempt to clean the lens using a lens cleaner CD/DVD with liquid and see if it resolves the issue(you can get one for as low as 5$). Perform a dry cleaning first(without the liquid) and then with liquid(two drops on the brushes of the lens cleaner DVD that pop-up after the dry cleaning run. If it doesn't resolve the issue then you may have to get the lens mechanism checked by a qualified technician. You can search the fixya repair directory to find one in your area.
