I have programmed several remotes mx-900 and mx-700's mainly on several Sony XBR2 and 3 model LCD's. I noticed the codes in the IR library and wrong. The discreet off for instance toggles the tv's enhanced surround sound mode. Also video inputs are either incorrect or do nothing at all. I updated my software just to see if there was an error that has been corrected, but no luck. Has anyone else noticed this and do you have any idea why the codes are so far off? It's not the biggest deal because sony codes are typically pretty universal across their line, so I just pick another model and pick the codes I need. Just wondering why this is.
