I use a Dune HD Smart H series. It is generally pretty good, however it has its issues. Will play everything BUT "Curious George" DVD's??? I originally used Zappiti as the user interface, however I find the text base function of just scrolling through my server much easier to read, especially for the all the saga like series such as the Lord of the rings, Harry Potter, etc. I recently found another Dune unit, a 101 on final clearance at a local computer store. It seems to work well and only cost $60! So I have that as well. Though it seems to have major sensitivity to type of HDMI cables?
