Actually it doesn't seem like it can. The Goggles RE actually support MP4 files.From the wording of that notice, it sure looks like the white Goggles are about to be discontinued - and hopefully replaced with an upgraded model.
I like mine, but it's absolutely ridiculous that I can't just pop in a standard MP4 or MKV SD card and play whatever I want. Really stupid, DJI, and could be fixed with a firmware update if you want to make your Goggles customers happy.
I can only give you my experiense - i use them for every flight, and never had a problem since getting them last year in July. They are awesome with not a single glitch.
