Low sales are exactly the reason. Several years ago, Warner Brothers really made a stab at trying to make music DVDs a viable market. It just never really paid off for them. Certainly releases with a 0 territory code and can be played on a PAL or NTSC player (which actually most DVD players today can read both formats) have the best chances for sales.

They distribute most music DVDs from other labels as well as having several great ones on their own imprint.

As a result, I rarely buy any music-oriented DVD's these days, cause it's not worth it to buy if I'll only watch it once.  Maybe others have experienced this.
