https://piefed.zip/c/politicalvideos/p/1152871/nuclear-bomb-any-day shows no video. The original link is https://lemmy.dbzer0.com/post/64472762 and has a video.
Be aware that PieFed changes the links. You need to copy the text, not click on the links in this post here.

A list with 4 entries: The video that didn’t show in markdown, a video from another site with the same syntax, again, but named, then an image, same syntax.
If the comments get parsed the same as posts, then there’s something with markdown.
