well i just got my nec 3500a drive and wanted to see if it was working so i put in lilo and stitch and nothing comes up when i put it in. it is not recognized when i look in my computer. i take it out, put it in my lite on dvd rom and it sees it fine. yes, this is the real dvd that i own. anyone else have this problem? the firmware has been updated and it is 2.18
