Help, I had an HR20 HD DVR runniing on a Slimline dish, the LNB head on it says AU9 and has 3 pickups (LNBs). 4 cables coming into my house into a flat rectangular box/switch, like 6 coax terminals in and 6 out. I was running a real old non-HD receiver and the mentioned DVR. Had 2 BBCs on the HD DVR. So, no SWM involved (I don't know what that is but have done enough reading in the last 2 days to figure I don't have it). I bought an HR24 and had it activated by DTV on my wife's system. She has an SL5 and a switch box and BBCs also. Her sewitch is different. It worked fine on her system setup as SL5, Multiswitch, use BBcs. NOw on my dish and cables and MS it will not pick up a signal. None, nada, nuttin! Tried for 2 days now and am going nuts. I have adjusted dishes before and acquired the signal in no more than 30 minutes using the old fashioned "systematic sweep method". Nuttin happening now. My dish is in the same place it always was, nothing blocking the path. What am I missing or doing wrong guys? Do I need to eliminate the multi-switch? I want to run just the one new HR24 and nothiing else, be able to watch and record HD simultaneously. Also, there was another SL5 (I think) dish next door with 3 LNBs and a built in SWM (says so on the green sticker on the head). I tried using it bypassing everything going straight into my HR24 and setting it on SL5 & SWM, or SL5 (SWM) and still nothing. Yes, I reset it several times. Thanks in advance for your help. JB
