i tried to tune our 10 foot dish to transponder 9 (5h or v?) the other day during the launch preparations... however, i was unable to get any feed at all... the secondary transponder 5 (3h or v?) was showing what appeared to be a multiplexed feed from some of the cameras... by multiplexed, i mean that the video was switching between at least two cameras several 10s of time per second...<br /><br />what's up? is this because of NASA's move to digital broadcasting?
