Hello
In fact, it is also free software can also be used, but not as good as the updating and maintenance of software billing software is good, I suggest you buy a full-featured free software for a long time used to be cost-effective than the free. In addition, I've used a lot of people will use the blu-ray ripper software, you can remove the protection of Blu-ray discs, burn DVD movies freely without restrictions, you can try.
