That is the same solution that is posted on the Macrovision web site.
That would work for a short term solution. My big problem will
occur when I get my Sony VHP-1270Q video projector
hung on my ceiling in another month or so.
There is a message on down this page from another 1270Q owner who is having
problems with Macrovision screwing up the video projector. This is with the output of the dvd player
going straight to the projector!

I am in this same boat. I will NEED to disable Macrovison in order to use my projector!

: Eric,

: There is no need for you to try to disable Macrovision. I was in the same situation with my TV having only RF in. So I used the VCR for the Video-In and had the same MacroVision problems.

: My solution was to use an external RF Modulator from Radio Shack ($29). This instantly fixed the problem.

: I hope this info help fix your video problems.

: : 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?
