Not sure how long this will last, but right now there is an audio feed from a NASCAR race from last year on audio channel 9 of both mix channels. The news mix channel has the race with commercials while the sports mix channel seems to have the raw feed with the announcers talking where the commercials should be. (If you have an interactive receiver, after selecting audio channel 9 you must go to the guide or keep some other on screen menu up to prevent the audio from auto-loading to audio channel 1.)
Maybe this is some sort of test to prepare for NASCAR Hotpass?
