I have:
April 26, 1989 MCA Showcase (if I'm not mistaken, this is the last show with Charlie)
July 24, 2009 Miami, Florida
March 18, 2010 Master Hall, Curitiba, Brazil
August 8, 2010 Chiba, Japan (it just has Wither and A Rite of Passage)
I also have April 6, 2000 Seoul, Korea from Trialoftears, but I can't get it to burn without giving me an error. :(
And as far as doing anything, just keep me in mind if you get ahold of any other cool DT shows. Cuz my collection is just starting too. :D
