As title says it keeps glitching or something...and i have to keep unplugging it...waiting like a min then replugging it in. What happens is After about a few days or so I cant do anything but turn on my tv with the remote. I cant control cable box, Or the Bluray player(nsz) ...nothing works...i cant even turn it off...is my unit defective or what? i bought it brand new not even 3 weeks ago...should i return it? been happening since i bought it...I am using it with a samsung tv and a time warner HD cable box.
