I have made a lot of download purchases through UMD, and a couple of these from different sellers are in QuickTime Movie format which on my system plays without picture, only audio. If sellers are going to produce these it is only right that this should be clearly indicated in the detail.
I mean they are. Every scene up for sale here indicates the name of the file(s) on the purchase page before you buy. So you can see if the file is .avi .mpeg .mp4. .mov (quicktime) etc.
You should check out VLC media player, it plays everything that I know of including older real media from places like Messyfun. I'm pretty sure thats listed on the page somewhere, I'll have to find where for you.
But yes, there is no attempt to sell you a file that you can't play, but you need to know what your file types are and what you can view if you don't use VLC.
To be fair .mov is just a container. It can contain video compressed with h.264, h.265, and even vintage cinepak. It's primarily a Mac-based format but is somewhat cross platform. A lot of iOS devices record in this format but its h.264 video inside almost always. For windows users, and even for Mac users, the recommendation for vlc is super solid. it's able to play almost everything including some super bizarre proprietary formats.
Your computer may also play any video files with QuickTime by default - I discovered this by accident. You can set the default video player for your computer to automatically choose VLC. Also, you may have the ability to set which player to use for a particular file. I have found that once a video plays in QuickTime, this setting is changed so that it always plays in QuickTime. I think you can change it for individual files also.

To add to this, it's not so much about the codec inside, but the proprietary Apple file headers in the container. FinalCut was notorious for that bullshit, as is Premier if you don't set it up correctly. The defaults in Filmora do the same thing. The key here is to NEVER use the default settings in any editor. Always generate your own rendering templates with the settings you actually want.
That said, I wholeheartedly second the VLC recommendation. Unlike the stock players on mobile devices, it doesn't fall on its face when presented with a non-standard file format.
