As if there weren't holes in this already...most of the releases that get widely distributed, on BitTorrent and on the street, aren't CAM releases. CAM means the audio and video came from the same, usually handheld camera. Telesyncs (tagged as TS) are shot from a camera that's almost always on a tripod, and the audio comes direct from an audio jack in a hard-of-hearing seat. So there's no way they could figure out where the recording came from.
Basically.
But more importantly, where can I get these cam rips that have such great audio quality required to figure out all this stuff, my movies always sound like such garbage.
