If you have any SWM LNB the guide data comes from the 101 satellite. If you have a non-SWM LNB, the guide data comes from 101 if you are tuned to a channel on 99/101, and from 119 if you are tuned to a channel on 103/119.
Jimbo is correct though, the worst thing you can do is keep resetting the receiver, because it will start populating the guide from the beginning again.
If things still don't seem to be working correctly, do a double reboot to clear the guide and then refresh it. Use the red button to reboot the DVR, then when the DVR finishes rebooting and returns to display TV, reboot the DVR again.
