I have this on both DVD and video and there isn't that much difference. DVD you can skip the guitar solos though and get back to David... or pause perfectly. If you do buy a DVD though, make sure you don't have the surround sound on. It sounds much much better when it's just flat together.  Although this isn't a concert like you'd see today, it's still entertaining, definitely a classic. Ziggy Stardust and the Spiders just go together. I've got friends that don't know Bowie, but do know Ziggy Stardust. This is a great band, wonderful character, wonderful songs, it all comes together despite the picture quality.  You can definitely just put it on and watch it, or work on something and just listen to it. It is worth the buy, especially if you love David Bowie.
