couldn't you have installed plex on your NAS, negating the need for the small PC?Depending on budget and technical ability
I built a small PC - specifically choosing all components with no fans so it's silent in the living room
I installed plex media server on the PC
I have a NAS elsewhere in the house as big capacity disks needed moving parts
I also have an Apple TV - if you Google plex connect - you can install a hack to turn the Apple TV trailers app into a plex client
Disadvantage - cost / complexity
Advantage - can be used with an Apple TV remote and very easy for the user
it's just a mybooklive so not in this case plus I don't want hard drives spinning in the living roomcouldn't you have installed plex on your NAS, negating the need for the small PC?
I think the point is being missed here. The OP wants to give his dad a usb stick with mkv's on. So all this talk of ROKU boxes/PLEX/NAS is a waste of time lol.
Some of the android boxes have USB ports for storage etc, so they would be able to do what the OP wants.
Looks ideal mate, although MKV is not listed as a file format and despite being called a 1080p media player, it seems the max output is 720p! (not sure if that matters to the OP or not)Something like this should do you, I'm sure it plays mkv files but I'll try and check it out later to see if it does.
