You are.
For commercial blu-rays it's been a 20 minute period. It can be set to whatever they want, though. For theatrical releases (i.e. not for home viewing) the limit is less than a minute. This is controlled by the Cinavia signal.
Thanks for correcting me. But the difference you're talking about is, AFAIK, actually two different Cinavia signals; the one in theatrical releases is interpreted by the player as "stop ASAP", while the one in BDs & DVDs is interpreted as "mute after 20 minutes". Still, that provides only two choices for the studios; unless there's a hidden timing field in the watermark, the studios can't vary the timing of the "stop" and "mute" commands like they can with Screen Pass.
The easiest way to play a Cinavia infected title right now is to rip as movie only and play on an HTPC: it consolidates fragmented files into a single file so no jumping around (buffering issues) and because of no menu, existing software can play it back plus Cinavia is not supported in the usual freeware software player apps.
I think you're confusing Cinavia with Screen Pass. Though both involve (a) detection of AACS removal, (b) a "copy detected" error message and (c) support by arms of Sony (Screen Pass was developed by Sony DADC, its disc-manufacturing unit; Cinavia is most commonly used on Sony Pictures titles), they are
completely different protection schemes. (Edit: In theory you
could use both on the same title, but AFAIK that hasn't happened yet.)
Screen Pass uses a combination of playlist obfuscation (i.e., fragmented files) and a lack-of-AACS app built into the BD-Java menu; the playlists can place the error message anywhere in the movie. Cinavia uses firmware in newer stand-alone players, or software code in PS3 system software and newer PC software players, to detect
both lack of AACS
and an inaudible steganographic watermark embedded in the audio signal; its player-generated error messages appear only in specific places (see above).
Fragmented movie files are a symptom of Screen Pass,
not Cinavia. Also, a movie-only copy of a Cinavia title will
not play in a player with Cinavia as the watermark survives virtually all user-initiated transformations (transcoding, analog copying, etc.)
Making a movie-only copy of the correct playlist takes care of buffering issues on Screen Pass titles, no matter what player you use. Using an unlicensed software player bypasses Cinavia, no matter what kind of copy you made (or even if you're playing the original with AnyDVD HD active), because it does
not contain the Cinavia detection code; the watermark is still there, but without the detection code it's useless.
P.S.: Let's shut this thread down. The OP is long gone, and it's turned into a Cinavia discussion which does not really belong in the AnyDVD HD forum.
