I know it's cheating, but I just cover the front of the remote when I hit the "TV" button. The 950 will not see the command so it stays off, but the remote gets switched over to "TV" mode.
The big thing that "chafes me raw" is that the volume control does not work when you have another source selected. I have to hit "SAT" to change the channel, and "AUD" to change the volume. A real pain when you are channel surfing.
