Query: No video on the Yoga CD's

This box is totally unnecessary if you have purchased the Ultra Simple Diet book. The audio on the CD's works just fine, but there is not video so it's hard to follow the yoga sequences. I tried it on the DVD just in case the disk was a DVD but to no avail. The box was a total waste of money. The Ultra Simple Diet book, on the other hand, was excellent. I tried to contact the Sounds True company who were responsible for the CD's, but they did not reply to my emai so I am out the cost of the box!
