Dual feed satellite tune


I'm tuning in a dual feed satellite for the first time.  I'm trying to tune in AMC10(135), G15(133), and AMC 11(131).  Any 2 of the three.  We got it tuned in now to AMC 10 and AMC 11 but the analog signals (c-span and c-span 2) have less than desirable pictures. All the dig. channels are working.  We are using a 3.8 m patriot sat.  This dish has been tuned in twice before and on both occasions the sats have been 4 degs apart.  The way we have it set up now the lnb's on the feedhorn are eqidistant from the center.  We are hearing now that maybe we should put one lnb at the center of the feedhorn and tune into a sat. there and then rotate the feedhorn to catch one of the other birds.  How does this sound?  I'm so close I hate to move it more than I have to.  Any comments or hints will be greatly appreciated.  And like I said I'm new to the game so you can assume I know little about it.

Thanks
