I just moved to an apt building which is not a MDU. There is one directv satellite on the roof that feeds the building. I just had the MRV service installed, and the broadband DECA for ondemand. Everything works great except that I can watch and delete other tenants dvr content. I assume that they can do the same with my dvr. I have tow H-21's and an HR-22-100. The installer said that the only way to fix this problem would be to mount another dish on the roof for my unit, or to change the building to MDU. I am renting and am not interested in attending HOA meetings to move towards the MDU solution. The tech support at directv had not heard of this issue, and I have yet to find anything on the internet to help me. Any other solutions? SHould this be happening? Thanks in advance.
