Well... I do have a 16:9 hi-def/Blu-Ray copy of the one-time HD telecast they showed on Palladium HD, so yes... I do have it on HD. Unfortunately, the MTV watermark is on it as well as everything else you saw on the standard/regular MTV broadcast.
There was someone selling cheep copies on ebay a few years ago on DVD minus the commercials. I think they got caught eventually, but it's a pretty nice transfer.
They were only allowed to show the broadcast a certain number of times (wasn't it like, six or seven?) and after that last time was done, they weren't allowed to show it anymore.
