I searched through the forum to understand IF cinavia watermark was used on movies I had (considering how much it is talked about) and how to detect the watermark. I don't remember the poster's name(s), but there was a suggestion of a notice during title preview. There was also the suggestion that it should probably say on back of bluray case. I tried with some movies the internet said had cinavia (like hangover II or III, don't remember others) and I didn't see any notifications of detection. After many searches, I found 'Friends with Benefits' bluray definitely had cinavia protection (based on cinavia logo on back). Using an ISO I ripped with anydvdHD of 'Friends with Benefits', I loaded into CloneBD (v188.8.131.52) and did a title preview play and the beaver (Bert) gave notification about 7-8 seconds into playing preview. Attached is a screen grab. I tried to do a disc copy with compression and ticked preview during encoding and Bert didn't complain. The only way I got Bert (the beaver) to notify me was to do a 'Title Preview' and play for 10 seconds or more. I understand better now and wanted to share with others. Hope this helps somebody.
