4 stars because attached hard drives may not be larger than 500 GB. Nowhere an indication, no message from the device. My other LG players (older) can do that. Otherwise, the player is very good. I use it on my Acer projector and the screen itself is very good with SD material from a hard drive. About Blu-ray and BD-3D you need to write anything. Here, the quality is excellent. No built-in fan, so on my projector. He also still has a normal stereo output that was important for me. 4 stars also why: "Producers should finally the USB jack / n Send to Back." Features such as Smart TV, DLNA, etc. have no meaning for me. Therefore, no test and no judgment.
