So, I recently installed an LG GGC-H20L Blu-Ray and HD DVD drive into the second bay of my mac pro. This in itself was an absolute pain, as I had to enable AHCI for Windows Vista by using a modified mbr because I was using one of the ODD_SATA ports on the motherboard which Windows doesnt' "see" cause it runs in legacy mode. Everything there went completely fine, as now I am running in AHCI mode and I can see the LG drive and I can play CD's and regular DVD's via that drive in Windows Vista. However, the problem now is that when I insert a Blu-Ray or an HD DVD, Windows doesn't even recognize that there is media in the drive. It says there is no disc inside. When I boot in OS X, I can clearly see both the HD DVD and Blu_ray (although I can't play it or do anything with it). So, can someone help me out trying to get Windows Vista to recognize the damn discs so I can play them! Please help!
