Query: Bad quality

The video was poorly burned, with many (at least 50) 1 to 5 seconds gaps in the film which made it very unconfortable to watch. The quality of the image and sound was also very poor. We finally had to stop it and put it aside.It is a shame for Amazon to ship and guartantee this type of products of such low quality.If I lived in the US I would send it back and have my money returned. In fact, if I can get someone to take it to the US and ship it back I will certainly do it.Gonzalo MartínezQuito, Ecuador.
