I have had mine for 2 days now and love it
I was playing mkvs on a 8000 series samsung 3dtv and they looked good
But there so much better on the wd the movement is smother and the gui works really well
The reason I got the hub was to play mkv's on my projector as well as my tv
The cover flow / film thumbs/ info is really good it found all of my 40 films I have so far but you have to do them one at a time , it doesn't take to long
The only bad thing is how slow it copy's from USB to it's internal hard drive
16mbs using a wd passport on my pc it transfers at 30mbs
All in all it's a brilliant little box that does what it should well worth £150
Also the remote is a bit slow my harmony flips through the menus at twice the speed
