those are agile tuners, so the sat in #2 can be feed your tv 1, or sat in #2 can be feeding tv2, etc. all of the decoding, compression and recording happens within the rcvr before it gets sent to the ouputs for tv 1 or 2. it wont matter what tuner you record on. so yes, "tv2" can record hd, and it can do it while tv1 records hd too :up
