This adds the following error message for VOD content with 4xx HTTP error responses
The protected video stuff is actually useless now, but I didn't want to make any significant plugin changes, so it'll be kept.
In order to fix VOD content, we'd need to implement YouTube's adaptive stream URL signatures. As said, I'm not interested in implementing this myself, so if someone wants this to be fixed, they'll need to submit a PR with working code and be willing to keep the plugin maintained.
Live content is of course still working fine.
