I ended up researching the wrong product because of the wrong name on this page. There are two seagate products like this - the FreeAgent Theater HD Media Player and the FreeAgent Theater+ Media Player.... The Theater+ is a network media streamer like the Popcorn Hour boxes, whereas the Theater HD only reads media off of usb hard drives and doesn't have HDMI and only upscales up to 1080i. This page is talking about the Theater+ and the name should reflect that.....

Have you noticed any pesky files/formats that won't play? The website claims to have a ton of compatibility but I was curious how accurate this is before I get one.........
