eye tracking & e-prime2

Hi all
I forgot to post my solution.

Not all versions of e-prime, clearview and tet talk nicely to each
other because they changed variable names with each new version. So
what I have working now is e-prime2 version 2.0.8.90 with tet 2.0.26
and Clearview 2.0.1.7.

Best,
Jan

Certainly, b) if it crashes even with just StartTracking (which is required anyway), there's no reason to think that video as such is the problem. So, it's a long shot, but have you tried updating yourTETpackages?

That is, exporting .avi at 25 Hz (or whatever framerate they are) writing out [originalname number], then making a loop over "number" with images showing every 40 ms, is pretty easy to accomplish, I should think (especially if you won't care about the occasional tearing).
