I have a wired network with great speeds yet anytime I try and play a downloaded video file it either doesn't play and says network error or it starts playing and anytime I try to skip to another point in the movie I get the same error. This is extremely frustrating as its a brand new tv 55uf7600 and works great otherwise but my fear is that the TV simply doesn't play certain file types. However it seems to be several that won't play. I've had this issue with MKV and AVI.
