  2. nope. Cinavia watermarking can survive alot more that simple re-encoding from lossless to lossy format.

    It's not removed, as Atak_Snajpera says. Streaming media players that aren't licensed for BluRay playback, like the Western Digital line of players, are not required to recognize Cinavia. BluRay players are not currently required to honor Cinavia flags on non-BluRay formats like MKV. Do note that some BluRay players may honor Cinavia on DVD and yes, there are a few DVDs that use it.

    Talking about Cinavia on DVD means DVD format with Cinavia in the audio, not MKV burned to DVD discs. Just realized that my point was not 100% clear.

    It is important to understand - are you suffer form Cinavia currently (i.e. is your player detect Cinavia or not)? - this is important as not many players support DTS/DTS-HD decoding thus they not sense Cinavia per se - DTS is workaround for Cinavia - as most of the player not dupport DTS (DTS-HD) decoding, audio track is passed as orginal bistream to S/PIDF(HDMI) output - this stream is later decoded in AV receiver however AV Receiver (AV amplifier) usually have no information about Cinavia and nothing is blocked.

  9. Different versions, different distribution model and different DRM rights (flags or categories).

    And Looks like Sony can decode DTS (DTS-HD) thus recognize Cinavia - LG probably not also it looks like for Sony who is both - equipment provider and content provider, DRM like Cinavia are important. For LG or similar companies not (as Cinavia increase price of equipment) - my advise don't buy Sony players.

    As Cinavia is coded in analog domain and currently there is no (open source) method to recognize protection and to remove protection only this can be advised - avoid Sony and similar behaving players.

  10. In this party here we guys are talking about removing Cinavia right?
    If so, you must be knowing exact methods of Cinavia watermarking as well. If you really know how it works then there is not a single sucker that survives in very first re-encode.

    Generally knowledge how Cinavia works is already known - small changes for audio signal phase for frequencies over 8kHz - small phase changes are decoded and based on this data bits are reconstructed - they trigger DRM.
