I just bought a Panasonic TU-HDS20 HD STB from Crutchfield's Outlet store for use as an HDTV OTA receiver. They state on the site that although this equipment may be a customer return, it is still warranted by the manufacturer as a new unit. I received my STB today and it looks perfect but I noticed that the Direct TV HU card has been inserted. I realize that this unit requires this card even if Direct TV is not used, but am now wondering if the HU card that came with the unit has been initialized by someone else? I do not plan on getting Direct TV now, but might in the near future should they start to offer all the local channels at no additional cost. I have spoken to Crutchfield who say that they will take care of me but still would like to know now, and not in six months, if I will need to get a new HU card, at an additional cost from DTV, should this one be used? So, how can I determine if this card has been initialized without installing Direct TV? Thanks for your help!
