Thanks. I think you're right, there's something not quite right about it. I'm thinking it's maybe collimation, but maybe not.
I use a two step process of data capture. I feed the camera's video output into a camcorder (MiniDV digital tape) and then capture it later via firewire into the computer. I'm going to have to check the specs of the camera output against the specs of the camcorder output to see if there's any "squishing" or stretching happening there.
As for going outside tonight I better not, I've got the flu something fierce, and I have to get up early...
