That's a new one on me... The 950's manual and the SL-9000 manual both make no mention of being able to program a macro into the source buttons. The MX-500's device buttons can have macros assigned to them, but you have to hold the buttons down for one second to activate those macros (which doesn't sound like what you are experiencing). You can learn additional commands to the source buttons (such as the "3" signal for your TV), but I don't see a way to do that inadvertantly. I suppose you might try using the "how to delete a macro" instructions with the SAT button, but it is a bit risky. (Undocumented tricks can be bad: there's one undocumented code for the 1050's remote -- 981 -- that wipes out all programming, but it takes the codes to control the 1050 out in the process, requiring a new remote.) You may want to pop on over to Outlaw's support page or call their tech support line (866-688-5292) and see what they can do for you.
