I have recently received this Alagna DVD from Nagiri Gmbh through Amazon. The format was PAL which I can't use. Nowhere in the listings from either company was a format mentioned. Only the front of the DVD was shown while the PAL format is shown on the back. Opera news has advertized the DVD which makes me think that it is available in NTSC also. None of the glowing reviews mentioned format. I have returned the DVD to Germany and am waiting for a replacement in NTSC or a refund.
