Kind of what my gut was telling me (from the Google Talk comments):

"I feel like a lot of assmptions were made in this lecture. We've thrown formulas out the window before because they didn't agree with newly experimental data. Using the schroedinger equation to prove the results of the quantum eraser is pretty much equivalent to using old newtonian formulas to prove that you can travel faster than the speed of light - it doesn't hold water. I'm not saying Ron Garret is wrong, but too many assumptions were made in this proof, i'd rather trust experimental data."

Still reading. Thanks!
