When it comes to 3D anything, it all rests on the quality of the glasses. If the red and blue lenses aren't the same color as the images on screen, then the whole 3D effect falls apart. NASA has released a bunch of 3D pictures of all sorts of things, from asteroids to Mars vistas, but the only red/blue glasses I have (from Spike & Mike's Festival of Animation featuring "Here comes Dr. Tran") just don't work well with the hues in the photographs. Meanwhile, there's a bunch of 3D pictures of Germany on Flickr that work nearly perfectly with my crappy glasses.

I suggest you fool around with the color on your TV screen, adjusting the red and blue filters and see if that might help the 3D effect work better.
