No, HD-DVD and Bluray don't count...both of them were too expensive, too limited and too encumbered by the format war between them, and never became as attractive as DVD.
I think "Were too expensive" is operative here. Blu-Rays are pretty cheap these days. You can pick them up used at thrift stores for a couple bucks each. If you deal hunt on Amazon you get get them for $5 new. Even UHDs aren't bad, especially if you buy in bulk. You can get the Alfred Hitchcock Ultimate Collection UHD box set on Amazon for $112. That's 14 movies, which averages $8 per film.
While it seems likely that he gave out the information in exchange for access to girls to rape, or because Epstein was blackmailing him, the chances of anything that harms Trump coming out of this are low.
He was involved with Epstein because of money. Epstein could funnel money to companies and organizations Andrew wanted funded. Getting girls for his friends was a side-hustle for Epstein. If you were that rich and powerful, you don't to to some money manager guy to get a prostitute, you just fly to Amsterdam. Now if you were at a party thrown by Epstein and there were girls there, and you are a sleazeball, you go for it.
There really isn't a lot of evidence of blackmail coming out. There might be, but I haven't seen any concrete examples, beyond rumor and conjecture.
It's great to be smart 'cause then you know stuff.
