I get far too much of this stuff:

I can take this file into Quicktime 7 Pro and re-wrap it; I can do the same in MPEG Streamclip, VLC or any number of other programs. However, YOUR stuff refuses to recognize any number of types of files, movs, aifs, mp4s...having to go to an external program and re-wrap a file (which I DIDN'T HAVE TO DO BEFORE the 2018 update) is counterproductive and lessens the chance I'll recommend Adobe products to anyone except the Trump campaign.
