Query: worst sound quality

I like a good detailed dvd when I'm exercising so I don't have to keep looking up at the tv to figure out what they are talking about. All I could hear most of the time on this one was echoing. It was like a video from the 80's I'm so disappointed. Just having a camera & a yoga mat doesn't qualify you to do a yoga video.
