If you look at the diagram again its the 2 links that connect pins to pins. There are only 2 links. Make sure you have those correct or the Xbox won't detect it. If you are PAL then 100% that is the reason. Always switch to NTSC if you are PAL. It will play PAL discs depending but they will mostly not support 480p or 720p. Some will, a lot won't. You are better to have NTSC rips to be honest. Some PAL discs are fussy and you will actually have to switch back to PAL to play them, or use auto region switching in xbmc4gamers. Even at that some will only play with the PAL region switched. I have a full PAL set of physical discs and have played many. You can switch easily. The enigmah app is probably the easiest
