Didn't work with my Yamaha AVR so it shouldn't be compatible with older codecs or anything like that. To make sure it works and isn't completely broken, I plugged it directly into the TV. The screen size is correct, plugged directly into my old Mitsubishi DLP. I tried adjusting the screen size, but even with a black bar all the way around the screen, the menu would extend off the edge of the screen. The sensitivity of the remote control is bad, sometimes it didn't move at all, sometimes it moved too far. very far. A SERIOUS pain when you have complex passwords. I would suggest setting up a bluetooth mouse and keyboard or something better. Couldn't get it to play Netflix like it was expecting touch inputs. May need a mouse all the time as I couldn't find a way to change the display scheme to show a cursor or highlighted selection. It's really hard to tell where it's pointing or trying to point to Google Play to add apps for example, it was basically a guessing game. I was trying to replace my Shield TV which broke over the weekend. My old Fire Stick is more convenient to use, albeit much slower.
