But these are not "factory" DVDs that you are talking about. I am referring to actual DVDs from the studios, versus bootlegs of dubious quality. Commercial DVDs must have either a DD or PCM soundtrack, and then any other soundtrack may be added (Such as DTS).
"Then it is a spot which came from the master and will be on all three captures, thus ending up on the output video. In this case, like noise, it will go through filters that will remove most of it, if not remove it completely. Spots like that are much less noticable during playback than big rainbowy laser rot spots."
Okay. I was just curious.
