Neither of the Sony 400-disc Blu-ray changers provide for loading a given changer slot via a predetermined sequence of IR codes. You are forced to manually select a given disc via the changers GUI instead. That being said, the Sony BDP-CX7000ES does provide for direct disc selection via RS-232. Unfortunately that would mean upgrading your TSU7000 to a TSU9400, TSU9600 or TSU9800 in addition to purchasing a RFX9600 extender not to mention paying around 3 times the price for the ES version of the changer instead. Certainly a tough pill to swallow for those of us with IR-based DVD management solutions who would rather not go to the added expense required per direct disc selection via RS-232.
