Bought my 1st HDTV, now need to upgrade thru DTV. I've been a long time customer, so am looking for a sweet deal. I want two HDDVR's. the 2nd for my cabin. I have 4 leads at home and 2 at the cabin (both on the same account). Will I need to change dishes/LNB's? I also plan to integrate OTA local channels. Any advice and thoughts will be greatly appreciated.
