The Limits and Disadvantages of UV System

There are so many functions brought about by UltraViolet, but what are the limitations, or say, what is UV system not able to do?

- UV will not play on devices which are not compatible with UltraViolet. That is to say, it is impossible for UV user to stream DVD to Apple iPhone, iPad, iPod Touch, etc.;
- UltraViolet is not a "cloud storage" platform, so it does not store files;
- UltraViolet files are usually DRM encrypted to disenable the copy or edition of movie content;
- UV system is only applied to the purchased movie content, not all DVD movies. Especially, it will never support Disney produced films and DVDs until Walt Disney Company joins in DECE.

Why Copy DVD when You Already Have UV Digital Copy?

1. DVD backup: UV system does not allow copying the DVD movie content, but just the playback on multiple devices. However, it is inevitable that kids and pets may "make motions" on the disc; if not, DVD may not escape from wind erosion;

2. Include Apple and Disney movies: Since Disney is developing Keychest format and Apple using iCloud, the two giants are not the members of DECE. So UV system does not support stream and download Disney movie to Apple iOS device.

3. Some concerns still exist in streaming, like slow speed, unsmooth playing, network dependence, etc;

4. What are streaming for playback is not real. They are virtual data stored on the server, so users are not the owners of the content.

So, in order to play any kinds of DVDs on any portable devices more smoothly without network connection, DVD ripper software is a necessity to rip DVD to iPhone, iPad, Apple TV, Samsung, Huawei, Xbox, PS3/4 and so on. Thereafter, there will be real DVD content or video file on the hard drive to enable movie backup, offline playback and video edition.

Disclaimer: Digiarty Software does not advocate ripping copy-protected DVDs for any commercial purpose and suggests referring to the DVD copyright laws in your countries before doing so.
