I’ll still argue that HD-DVD is mostly the better technology. The things which BRD tried to claim were what made it better were not things which would fundamentally have stayed with BRD. The interactive layer was finalized first on HD-DVD and was better.

All that said. I have many HD-DVDs and the drive. Before my drive fails, how would I archive my movies. 🤔

As a general rule of precaution, don’t follow links in the email. Instead go to the website directly, maybe from a private or incognito instance, and reset it directly. If the email is valid, you’re doing the same thing and if it wasn’t you aren’t drawing attention to anyone else.
