Given my TV is a smart TV and I have a Fire TV and don't play games, is the Dune a better bet than the Shield for video ? What I like about the current Dune HD Solo 4K I have is it plays Blu-Ray ISOs with full menu and SD is very good quality and it has VXP, but sadly being HDMI 1.4 it is limited. Is the Dune Pro 4K a worthy upgrade at £200 ? Or does the shield beat it hands down for video streaming ? Can the Shield play Blu-Ray ISO's ? Both are around the same price.
