Hi OP if its any consolation I have just got an xtrend 1000hd and have found same problem as you, poor pic quality. Did you resolve it and if so how? Also with the 4 tiners have you gone 2 x sat and 2 x C hybrid. There is a reference in manual that says a certain congig cant be used but it has me a bit stumped. I am awaiting 2 x hybrids. VIx image 4.1.16 or june cant recall exact numbers.
