I've just recently replaced my Xbox Philips DVD ROM drive with a Sony DDU1612, as per these tutorial instructions: http://dwl.xbox-scene.net/~xbox/xbo...the_Xbox_DVDROM_drive_with_a_Sony_DDU1612.pdf The good news is that the drive ejects, and recognises and plays my divx CDRs without a problem (yippee!!) but the bad news is that it won't boot from a game DVD or a video DVD disk. The strange thing I have noticed is that when I browse the files on the game DVD disk, using XBMC, it does not show any of the XBEs. Is this why it can't boot from the game DVDs?? Is there something about connecting this DVD drive to the XBox that I've missed?
