Can anyone attest for the quality of this DVD? It looks to be among the first wave of releases done by Rhino way back in 1998 and I'm wondering if there's any chance or need for a new, upgraded version? Would you say that this title is a safe purchase, or is there strong possibility of it being revisited in future? Has the audio/music been tampered with in any way? Is it complete and unedited, orig. a.r. and so on? I'd really like to pick this DVD up and plan on doing so this afternoon, but I just want to make sure it's not a product of it's time and up to the standards of current DVD releases. Thanks!
