1/5 HD DVD Disc Will Not Play
  by Elder Dave (Greenbank, Washington United States)
This is sad. I have ordered five Opus Arte HD DVD discs relating to opera and ballet; three play very well ("Swan Lake", "A Midsummer Night's Dream", and "Die Zauberflote"--excuse the lack of umlaut. Two would not play: "Die Fledermaus" (since withdrawn) and now "Il trovatore". My Toshiba A3 and A30 both produce the error message: Cannot Play the Disc/Error Code: 408bcOOd. My LG BH200 lets the disc get past the copyright warning and then continues to play a one minute loop in which the camera pans across a line of canons in a red mist. There is no audio and there is no button that will break the disc out of this loop. No menu displays. Needless to say, this is VERY disappointing; I've been looking forward to this disc for months. I see Opus Arte is releasing La Boheme at the end of April. I was ready to order it, but I'll wait until I see a review that says people can play it. By rights, this disc should have zero stars. Naturally I'll be returning it to Amazon for a refund.
