The 950 uses a Universal SL-9000 remote, which was designed shortly after DVD reached the market. I believe this is why URC made this mistake.
What I did when I was using my old 950's SL-9000 (before I moved to an MX-500) was to learn the transport commands to the surround mode buttons (the unlabeled circular buttons toward the bottom of the remote). A fine tip Sharpie can ID what transport command you assign to each button.
