But I think some movie content gets processed so as to reduce crosstalk on the displays prone to that. Reducing high contrast areas, I think, and maybe something with the color. So some movie content apparently will show less crosstalk than other. I'm a DLPLink guy, so I've never seen crosstalk.

This may be true... I think some content is mastered with active shutter flickering in mind as well, for example, and adjusted to mitigate its potential.
However, addressing and minimizing the potential for issues on particular systems due to the weaknesses & calibration of those systems is very different from those issues being inherent in the content itself.
I am aware of no 3d blu-rays (except anaglyph tech) with crosstalk "baked-in". This would require encoding at least some of the left channel information into the right channel stream, and/or vice versa.
I would assume cable & satellite would also be fairly safe, as I can't see how a left or right eye signal would "bleed" into the other on the transmission end of a SBS or TnB broadcast.

You points all makes logical sense to me, however my personal experience does not prove that to be the case. With my Sony active 3DTV content clearly seems to play a role.
All of the 7-8 blu-ray discs I've tested show minimal ghosting. There is the occasional scene here and there that will show some, but 99% of the time the picture looks perfect. However just about anything I've watched on my cable provider's 3D channel has significant ghosting. Video games as well have a fair bit of ghosting.
My expectation is that if my cable provider showed a 3D movie in SbS format it would have significantly more ghosting than the identical film on blu-ray. I hope to be able to test my theory one day soon, but so far the SbS content broadcast on cable is BRUTAL for crosstalk/ghosting, yet blu-rays looks beautiful.
I'm not sure technically why that would be the case, but it is.

But is it actual ghosting, or an issue related to the offset of the L/R views? I suspect broadcast SBS & TnB would be more succeptible to this kind of issue, because the content is half-frame, then stretched to restore proper aspect, then overlayed... and the last steps are done by the display device or processing converter, with no ability to account for underscan, horizontal/vertical image shift, etc., at the source.
I've encountered doubling from broadcast sources as well, but when viewing through one lens it disappears, which indicates that it is due either to excess parallax, or to offset issues, and not true ghosting.
