My universal disc players; Mcintosh MVP861 and Pioneer Elite DV59vi will only play the CD layer of the SACD's I put in. They both play single layer SACDs with no issues, so I can't figure out why or how to get them to play double layered discs as SACDs. These were both fairly expensive and decent players. I've gone through the settings and menus for each player, over and over again. Any suggestions or advice about this?
