You're close, I think: HDCP only applies to the HDMI output, but DVD players typically insert non-standard crud in the vertical interval of the analog outputs to prevent VCRs from locking to the video.
This is an occasional problem at my church: we will need to play a teaching disc for which we have bought rights to show, but our video system won't pass the video through to the projectors.
We have solved this by running the video through a processing amplifier that regenerates the sync and blanks out lines 10-20. We happen to use a Grass Valley 3240, which is an NTSC model; I believe that the 3241 is a PAL version. You can probably find one on eBay, or a local television station might have one sitting on the shelf now that analog video is largely a thing of the past for broadcasters.
A proc amp like this is actually designed for composite video, but you should be able to the Y (luminance) channel through it and accomplish the same result -- you would need to turn off the chroma. The delay on most proc amps is minimal, so the luminance and chrominance should still be pretty well matched up.
