So after going through the forum, there were only a few threads that asked the question whether AnyDVD can decrypt BDs in the background for ripping when not connected to the internet. I think the short answer is no, for newer discs anyways. It also stated that one option would be to have it connect to OPD just once where the .dt1 file will be created in the cache folder and it can be used for offline use. Does this .dt1 file work for only that one disc that asked OPD for the decryption info, or will that file also work for all BDs prior to that .dt1 file creation? In that is the case, reconnecting once every few months would update that .dt1 file. Advice on this would be appreciated. I don't know too much about the technicalities of ripping in general.
