Yes, you can watch videos with the box and the picture quality is respectable. But if you want really comfortable home cinema in 4K without hooks and eyes, then you will quickly reach the limits of possibility. The installed XBMC is totally bugged, as one is used to from China products. Connections to SMB servers are either unreliable or does not work at all. The resolution can not be customized. The list of mistakes is long and has nothing to do with a cultivated entertainment.
For people who have to look at the purse, like this media player to be a viable alternative. Do not interest me, such "solutions" simply.
