My inlaws have an old sidecar dish and it looks like the jumpers between the 110/119 LNB and the main LNB assembly are failing. Can I unplug them and setup the HD DVR's as if they had a 3 LNB Slimline? I ask because they are getting an error on the DVR's about guide data. This is a non SWM install, 3 HR DVR's. No international channels, located in the Los Angeles DMA. Any help is appreciated.
