I'm very glad to see Slysoft finally address Cinavia. I hope that it will shut some people up but, sadly, it probably won't. Some people are never happy and live to complain about anything and everything.
With the above being said, remember that CinEx HD also has a SoundTouch function that doesn't require the use of a database. At present there are about 183 database files for CinEx HD. They total in the area of 16.8 GB. That's definitely a turn-off.
I haven't taken the time to play around with Cinavia removal - because it has zero impact on me - so I can't comment on the quality of any of the solutions. Anyway, it's certainly great to have another option for Cinavia removal for those who need it!
