I am having difficulty getting my new Samsung smt h3362 to respond to my ir extender, which has hitherto worked perfectly with a Harmony 650. It responds to the Harmony without the extender (i.e., when the cabinet doors are open), but somehow cannot read what the extender is putting out despite moving it to different locations. Tivo, receiver, Blu Ray all have no trouble reading the extender. Any suggestions? It's a NextGen extender by the way.
