I was watching a ripped Spiderman years ago on my PS3 and the PlayStation refused to play it after 10 mins with an antipiracy message. This was via a network video server. Don't see why Sony would have rolled back that feature since.

This is Cinavia audio watermarking. It's designed to survive lossy compression by staying within the human audible range.
> If a "theatrical release" watermark is detected in a consumer Blu-ray Disc audio track, the accompanying video is deemed to have been sourced from a "cam" recording. If the "AACS watermark" is present in the audio tracks, but no accompanying and matching AACS key is found on the disc, then it is deemed to have been a "rip" made by copying to a second blank Blu-ray Disc.

Edit: that same page says its now a requirement for all consumer bluray players to use this tech. But I don't remember seeing those messages for years. The pirates must be winning with their methods of changing the signatures.
