Query: absolute nightmare, avoid at all costs

First of all, there are NO instructions anywhere on how to use this product. No matter how hard you try, with any DVD, copied from any other source, you will constantly hit a wall that says there is an error and you will not be able to duplicate a DVD. This is an absolute nightmare of incompetence and an out and out con. Look at the ratings for this product and DO NOT WASTE YOUR MONEY!!!
