Example Output: Negative

Example Output: Positive

Example Input: I have had the first DVD since I bought my first dance hoop over a year ago, and figured that I would give the second one a try. This DVD is horrible! The picture and sound quality sucks. The picture is grainy and the sound is off. I could have made a better DVD in my backyard with my small camera. It is over-priced and they could have fit so much more in one DVD. I am so dissapointed that Hoopnotica would put out such a low quality product.
Example Output:
Negative
