i agree guitarguru, i prefer DVDs over CDs. live stuff is always best video.
also Nevermore's DVD must NOT contain fast motion shots constantly. it gets me bored easily cause i can't focus on a member for a while or the whole band. when you see a concert you aren't running around on stage or anything. a live DVD should give the feel of a concert. focus on a few members, cut to the drummer, cut to a close up of one member. all the cuts should be at least 30 seconds or so. no 1-5 seconds. the less the motion the better. they did this shit on the new In Flames DVD along with the Lamb of God DVD.
the fast motion causes a more 'music video' effect rahter than a concert effect. the music video effect makes it seem like the audio isn't from the same concert or something and the video is just placed on top of an audio track, rather than both being recorded at nearly the same time.
just some advise i hope you and other bands take when making a live DVD
