DVR Not Recognized as a DVR

I had my uverse installed in the beginning of September. After the first week, the DVR (VIP1225) erased all of the recorded shows. Didn't think anything of it untill it happened again last week.

Tech support said that they DVR was faulty and they mailed me out a new DVR Box, I got a VIP2250. Plugged it in last night and now the system does not recognize it as a DVR Box, but the box works as a regular receiver. When I press record, it schedules the recordings but it doesn't record anything.

Call tech support back and they now say it is an issue with the wires coming into the house, which I find hard to believe becuase I have no issues with my internet or TV service. Is there anything that can be done to reset the system?

Support scheduled a technician to come out to my house, but said that they would not provide me with another VIP2250 as they are only for the U450 customers and I am only a U200 customer, could it not be recognizing it as a DVR becuase I don't have the required channel package?

Thanks.
