Mibox or Jetstream

Any recommendations? I'd like something that can stream remux copies of blu ray movies.

If these are 4K Bluray Rips - you need a device with Gigabit Ethernet for those sort of bitrates.

WiFi will not usually be reliable enough and 100Mbit only Ethernet is not sufficient for 4K Bluray Remux's.

My sisters have zero problems streaming off my Plex server via FireTV Sticks. But if you want something slightly better, then go with a Mi Box.
