Some guy on Ebay is trying to pass off a set that is Digitally Remastered with 5.1 Sound. I wasn’t aware of any set like that. Here’s the link. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&category=617&item=6400411497&rd=1
And he says there on Dual Layered DVDs. It sounds like someone just edited the Dr Gonzo set and put the extras specific to each movie on their own discs.
