Picked up the x700 on Thursday from Best Buy and was really impressed for the first few days. Apps were more stable, Vudu app has UHD playback, etc. However, freezing issues have begun. Was watching Transformers The Last Knight and it froze at chapter 16 every time I tried it. I even tried going to chapter 17, 18, 19 manually and still froze. So, I thought it was the disk, popped it in my X800 and it is flawless. Was able to watch the whole movie without a hiccup. I guess Sony has not ironed out the BS it had with X800. Gonna take it back and wait for something better. Very disappointed in the Sony 4K players.
