1) The verified the SATA contoller is not in AHCI mode, it is in native IDE mode. Ch1Master is a DVD burner, Ch1Slave is an external HD (ESATA connection), Ch2M is the old Bluray burner, CH2S is the new bluray burner, Ch3M is an internal HD, and Ch3S is an internal HD.
2) I can explore the disc content on both old and new burners even though it reads DVD-Ram on My Computer.
3) The only box that is ticked is the "enable Bluray support".
3) The setting on ImgBurn is "AWS". In the past on the old burner I tried to slow it down to 1x speed, but it wouldn't allow it to burn at that speed once it started.
BTW, I burned another disc, District 9, on an old BD-RE that wouldn't work anymore on the old burner. It came out fine and works on the old, the new, and the standalone. It also reads correctly on My Computer as District 9.
I wish things made more sense; there doesn't seem to be any rhyme or reason to it. Thanks for your continued support and suggestions.
