@j @Humpleupagus @Noraweed @TeaTootler @bajax @lanodan The ones you upload seem to be, or they were until this last one that had working video but not working audio.

"Youtube is owned by Google and is shitty fluoride crammed past everyone's teeth" aside, they have completely different incentives. They are a video streaming service that sells ads: they don't want you to keep anything around and they don't care if what they serve you this week can still be decoded next week. This seems obvious.
