For what it's worth, the DVD is listed as Region 4 on chaos.com for the DVD-only release. It does not specify any region code for the deluxe set, although I would assume it is the same DVD put in a different box.
That still doesn't explain why this DVD does not play in my player, which plays everything else I have thrown at it that is NOT "region free."
I sent that email to getmusic on a weekend. I don't expect to hear (if at all) till next week.
I'm certainly not going to return the whole thing, as the CDs work perfectly. Although I will be very disappointed if this DVD issue does not get resolved.
