I live in a condo building that shares a single dish (to eliminate everyone and their brother hanging a dish off their balconly). The signal is distributed to the units through a couple of 6x16 wide band multiswitches and a couple SWM-8s. We recently had someone new move into the building and is having a heck of a time getting their DTV service activated. The install techs insist we are an MDU but each unit has their own account and manages it separatley. From that standpoint we ARE NOT an MDU. But the techs said we are wired like one and insist that the receivers they have will not work with our set up. I find this very strange since there are multiple other units who have their service hooked up and have for quite some time without any issues. Supposedly the techs even hooked up a receiver and went through the setup process but it would not complete and asked for some sort of waiver. For all intents and purposes, we are wired like a large house with 11+ receivers (we're a small building with only 11 units). Can someone please help? Why would a new receiver hooked up to the setup now not work? Has DTV changed something in the receiver software recently that would cause this?
