: Macrovision is a major downside to an otherwise good optical disk video format (dvd).: I just got my Panasonic A-110 dvd player and am unable to watch dvd discs without seeing Macrovision
: picture fading! I am forced to run the dvd player through my vcr because all the tvs in the house
: have RF in only. The vcr is the only device that has s-video and composite video in along with an RF modulator
: to create the RF signal needed for the tv. I am only trying to watch the dvd discs that I paid for.
: One solution is to buy new tvs.
: The other is to modify the A-110 to DISABLE the Macrovison rather than filter it out after it has been
: inserted into the video. : I noticed when playing a dvd that even in PAUSE mode, the Macrovision was still changing the video
: signal. This suggests that the Macrovision is not encoded on the video stored on the disc, but that
: it is being added to the video signal by the PLAYER! Judging by the "digital brightness rings" in the
: paused plusing video, it looks like the Macrovision is being added to the video while it is still a
: digital video stream and before it gets to the NTSC encoder. : I wonder if:
: 1. the Macrovision process is done by one chip in the dvd player
: 2. the Macrovision process is integrated into the NTSC encoder chip
: 3. there is a pin on one of the chips in the dvd player that is a Macrovision ON/OFF signal that
: could be changed with a pull-up resistor or a pull-down resistor. : Does anybody have any Macrovision modification information yet? I think this information needs to
: get published somewhere! Anyone know? : Eric Koester Macrovision modification information can be fou at this address:
