I haven't seen the DVD as yet, but I did buy the VHS when it came out, and it was excellent.  Great sound, good visuals and pure Floyd music.  "A Delicate Sound of Thunder" was fuzzy in sound and visuals, but this one is not at all.  I did order the DVD, and I just hope that it's that much better.  If you are a Floyd fan, you need this concert.  In addition to the new stuff, this CD also has the entire "Dark Side of the Moon" performed live.
