Where i install the elevation for DTV 3rd generation lnb is 35. for a dish 500 it is 32, and for a dish 1000 it's between 28 - 29. so some trees could be a LOS problem for dish but not dtv. He might not have been BS-ing you.
is it possible to record something to the dvr hard drive from the built in OTA tuner? by setting a manual timer maybe? don't have a 921 and i'm curious.
