I can understand your confusion. The Jewels documentary is not the same as the Jewels dvd. The documentary was shown on Japanese tv in 2004 with a lot of concertfootage. The official Jewels dvd contains promo videos.
So, they are simply two different things with the same name. I hope this helps.
There's some great live footage from 78-79 in this documentary, and it has never looked or sounded better.
Don't wait for it to be shared here. If you really want it, then search around the internet, make contacts with people, and get it in a trade.
