Well I upgraded today. Got rid of my 811 and 625 and ordered two vip 622. Well they were out of 622 and I got 722 instead. DARN. Yeah for me. Anyway I also have a 311 that I wanted to replace with a dvr510 that I got from a friend. The 311 works fine but the dish 510 can only find one satellite. The tech told me it's probably a bad box. Is there anything I could try. Keeps telling me it's hooked up to a twin dpl when it's hooked up to a dish 1000.
