If you don't mind spending (slightly) on a new hardware, Roku Streaming Players or Amazon Fire TV Stick are both a fantastic option.

I understand you are looking for a elegant command line solution. However, if you use MKVToolnix, you can load the first TS file and append (merge) an unlimited number of ts files to be muxed subsequently in order into an mkv (for example 10, 5 second ts videos will mux into a 50 second mkv).

For iMovie 10 and above:
Drag and drop the clips that you want to show at the same time to the timeline and make sure one is above another in the timeline.
