OK, so I just tried to watch 'Justice League' on the ATV4 to check out the service. A bit of jumping around is required to select a rental via a browser first then sat back to watch the film...
I get a 16:9 aspect ratio event with stereo sound only in my home theatre!
Am I missing something here or is that how all content will be delivered by Lightbox (no wide screen and no Dolby 5.1) ?
Edit: Checked the facts on this film and it was released in 1.85:1 so the aspect ratio is correct. However, the lack of 5.1 will push me away from these offerings if this is the case.
