Query: Avoid Ultraviolet at ALL COSTS!

Hangover II is an excellent movie, enjoyed it from start to finish. However, I regretfully have to give this product a one star review thanks to the Ultraviolet digital copy included with the Blu-Ray. Until recently, purchasing a digital copy meant downloading through iTunes and sharing with whatever device you pleased. With that being said, Ultraviolet requires that you download two programs onto your computer and make several new accounts. Once you complete all these steps, you can download the file in an MP4 format. Unfortunately, the MP4 wont play in any programs. I can't even figure out how to play it in one of the programs required for download. Hopefully, the creators of Ultraviolet will realize the error of their ways and understand that consumers want to choose how they download and view their movies. Until then, avoid Ultraviolet at all costs.
