I recently had to purchase a SWM5 LNB on my own because like many DTV was unwilling to help their long standing customers with the SWM upgrade. I have the 3 prong LNB right now for HD/DVR. Due to my HOA we had to get rid of the second cable outside our place and the SWM was the only solution. I now have the SWM5 LNB in hand and am going to install it. I have only one HD DVR receiver and internal cabling in the house. The DTV tech said it should be an easy swap of the LNB and plug straight into the DVR which is SWM compatible. I've been reading other posts about splitters and power supplies but they were all in conjunction with multiple receivers. Do I need any of these items? My understanding from the tech was I only needed the LNB since the DVR was compatible and I only had one. Also, once I swap the LNBs out, do I need to reprogram the receiver? Or can I just pretty much plug and play as before? I don't want to lose anything I have now. Any info will help. Thanks.
