Given the age of the last official SlySoft release of AnyDVD it's a given that there are newer or tweaked protections that cannot be properly handled. Furthermore, there was a transition from the SlySoft OPD (Online Protection Database) to a newer RedFox OPD which also saw some changes in how it functions. Older SlySoft version owners were given a grace period before the SlySoft OPD access was ended. For AnyDVD to handle the most up-to-date protections one should be using the latest version which would be the latest RedFox release of AnyDVD and have access to the RedFox AnyDVD OPD.
Note: Even given the fact that the final SlySoft release of AnyDVD can no longer access the OPD it still handles a huge amount of DVDs without issue. Newer DVD releases since then or some oddball releases not encountered before might pose an issue but it still handles a large amount of discs. But, it shouldn't be expected to handle John Wick: Chapter 2, for instance. With respect to Blu-ray then the final SlySoft release is going to show its age more quickly due to the protections used and the industry putting more attention into thwarting backups of Blu-rays these days.
Without rehashing an already over-rehashed discussion, the loss of SlySoft was big but beyond the control of anyone. It happened and it hurt the entire community that wants to protect their investment in physical media. Those involved with SlySoft could simply have bowed out and walked away and never been heard from again or... carry on the torch. Thankfully, key developers and staff decided on the latter but to do so required, unfortunately, having the infrastructure to support development which involves servers, money coming in, and the ability to pay employees. So, sadly, new RedFox licenses were required which are
not insanely priced and were discounted when the transition took place which was quite some time ago now. Anyone who has used AnyDVD knows that it winds up paying for itself and is a constantly updated, supported, and reliable.
I highly recommend reading at least the first few pages of this thread:
https://forum.redfox.bz/threads/no-fox-no-job-no-future.68331/ with special attention to the questions/comments made by former SlySoft and RedFox Project members. The thread, frankly, covers nearly everything there is to cover.
I'll quietly move on from this thread now unless there is a specific question pertaining to something I said but we do not need another never-ending discussion on how RedFox was wrong, etc, etc. We're not beating a dead horse again.
NOTE: I do not know if CaribbeanBlues edited the original posting but my impression is that it was given d00zah's reply and I only see the "Further testing..." post. I am
not attacking CaribbeanBlues with my response. I'm merely presenting what has occurred and only what I can see about this thread.
