Yes, absolutely, I always read reviews for audio and video quality especially if it is going to be a double dip.Both of you probably know this already, but it bears repeating... Just because something is on Blu Ray, doesn't mean it will have high-quality picture and sound. Sometimes the Blu Ray release is just a copy of the DVD. It pays to check out online reviews before buying!
While I'm here, might as well toss another into the ring for its undeniably high-quality performance:
John Mayer - Where the Light Is (Live in Los Angeles)
I am a big John Mayer fan and love that album, the audio and video quality are excellent.
