The original "Colour of War" series was made by the BBC a couple of years ago and this is still available on VHS and DVD.
The "Anzacs" version is a co-production by Nine Network Australia and TVNZ and sold by Film Australia (VHS and DVD versions), and I can recommend it. The DVD I have is for zone 4 and PAL, but doesn't say anything about being available in NTSC or other zones, but does list a contact at

I understand that most new DVD players these days will play multi-zone and multi-format discs, and it they won't, your DVD-ROM on your computer will.
