question:
Poor video quality . I purchased this product to benefit from dvd technology.  The reviews on the website led me to believe that this product was somehow updated, or upgraded for use with dvd technology.  Last winter, I ordered the video, which is is like a pirated version, with very low resolution.  If I could, I would return the two dvds I purchased.  I feel ripped off and stuck with an inferior product.    I love callanetics content.  Amazon should be urging this company to provide new material.  It's no help to see a sticker on the dvd I purchased announcing new products in Dec. 2006, which is when I purchased two inferior Callanetics dvds
answer:
NEG
