I keep seeing posts about whether this game or that movie displays crosstalk. Isn't crosstalk 100% dependent on the display device?
If the display device has no inherent crosstalk, I don't see how the content can affect this, unless there was some error in the authoring of the disc that placed content in the wrong frame.
Yep. Aside from a few uncommon exceptions, it's the glasses and/or TV's fault if they can't handle the technical demands of deep, vibrant, high-contrast 3D.
Content is only "at fault" for crosstalk in the same way the high-quality graphics profiles on modern games are at fault for causing unplayable framerates on an old PC. PC gamers can either turn down the sliders to improve performance at a visuals expense, or get a new PC; just as 3DTV owners can either turn down stereo depth and the TV's brightness and contrast levels, or get a 3DTV with better crosstalk performance.

Every once in a while we would have to make an adjustment to hide or reduce "ghosting" of a bright light in the background. Ghosting is an artifact of projection, not photography, but we decided to mitigate it in the photography to improve the experience in the theater. Hopefully, as projector technology improves, we can forget about that.
Also, on Blu-ray 3D, you have a main view (eg. the left eye view) and a 'difference/dependent view' (eg. it takes the left view, uses the info from the encoded 'dependent view' to generate the right eye view). The left and right eye views are not encoded entirely separately - one view is - but the 2nd uses info from the first. In theory, if not enough bitrate is given to encoding the dependent view, wouldn't you see parts of the other eye's view - no matter how good the display/glasses were?

Bitrate starved video just blocks up. What could happen is the left image would have compression blocks in one spot while the right image has compression blocks in a slightly different spot, and then you'll see an annoying shimmering effect.
2D encodes reference previous frames to draw the current frame, and 3D movies reference the left eye to draw the right frame in much the same way. I doubt a 3D encode would ever double elements of the left image onto the right image- it would be just as likely for a 2D movie to double the image from frame 214 onto frame 215. So the codecs have demonstrated over time that they know well enough how to isolate one image from the reference frame.
I watched over 20 3D movies and documentaries on one of the 720p 3D DLPs and not seen any crosstalk whatsoever. I've certainly seen it with 3D LCD T.V.s. I'm using the Nvidia glasses (5 pairs) and they've never produced crosstalk either. Everything I've read indicates that the problem lies almost entirely with the display technology. LCD has the most problems, then LcOS, Plasma and last with very, very few if any problems is DLP.
