This DVD was released two weeks ago. The sound is ok but the sound mixing is strange. Diana Krall sings and plays the piano at the same time but the vocal comes from the front speakers and the piano from the surround speakers.
Diana Krall in Paris Concert DVD
I'm not sure how long it's been out but for Diana Krall fans The "Diana Krall in Paris" concert is great.I had a chance to watch it last night and I'm impressed with the 5.1 Dolby Digital mix, better than the DTS version.
