I purchased and OTA adapter that plugs my antenna into a USB port on the hopper. It found the channels and put them on the guide and shows the programming. Everything works as it should except quite often I get a box that pops up saying Attention 978. Detected a device that has stopped communication. Reset is requited to resume.
I have checked my connections and everything seems ok. I purchased this device at Sattleite City and they told me it was completely compatible with the hopper I have.
