i only have the hdd that came with the xbox you havent got the dvd player software installed i think your best bet is to do a search on google and look for slayer auto installer 2.5
create iso using craxtion u can get that at
www.craxtion.com and other places just do a search burn it with nero very very slow as an image on a dvd or cdr that you know will work on your xbox
or you will have to ftp the software for the players and stuff to the e: on your xbox after creating the apps folder and such i'd go with slayers and just install dash and all apps to the xbox all you do is put it in tray and then boot up with the disc in it
