Wrong positioning in flat angles

Hi everyone,

we're using AR Toolkit version 2.61 on a Linux System and have problems with the positioning of the object, 
when the pattern is held in flat angles towards the camera.
The object "jumps" on the y-axis, when the pattern is moved just a little bit around the y-axis. Or the object is 
drawn in a complete wrong position. 

When the pattern is held in an bigger angle towards the camera, the effect doesn't appear anymore and the 
object is drawn correctly.

I hope someone has got a solution for this, it would be great. We don't think it's a problem of our application, 
as this "effect" appears in the demo-applications, too.

We use a Digital Video Camera connected to a TV-Card using a S-VHS - cable.

Many thanks in advance for any help!

Sascha Häberling
