I have another fancy stereo up-conversion for you, with Trailer 2 of Valerian and the City of a Thousand Planets. Even as an acronym that would be long: VATCOATP. If you prefer the stereo mix, it is included in the .mkv file as the 4th audio track. Trailer 2 can be found at the VATCOATP page.
My apologies if this comment doesn’t have anything to do with your post but I was wondering if there is a way to find the Matrix in Lord of the rings trailers in 5.1 ?
I think they are very cool trailers
