You can do both,
-either create a disc with mfe plus a fews media files in it (bootable disc)
-or load a homebrew laucher first, a disc that loads gcos or sdload,
launch mfe with it and then swap it with the disc containing the media-files
If you want HDD support:
-become an offical developer
-write a mediaplayer with the sdk
-and get hold of a RVT-H ^^
