How is the signal strength (indicated by the on screen display, and used for dish alignment). I think that different channels come off different satelites, and although they are close enough that the dish (oval one) can receive them all, the dish alignment may be optimized for one and be poor for the others. I believe that "Tilt" (rotation around pointing axis)is the axis to adjust for this.
By the way, although I am an engineer, I don't claim to be much of an expert on this subject, but I have just gone through the process of installing a Direct TV rig. I encountered no problems whatsoever.
