Okay great! thank you for your help.
Do you know what this equation ectually represents? I can't find anything about the physical meaning, or a derivation of this equation. I tried searching on conveyor belt equation but got nothing.
Thanks for your reply. The equation you got for X(x) is the same I tried to solve. Let's do it again:
\lambda^2+2VX'\lambda + (V^2-c^2)X''=0
has solution
X(x)=\exp\left(r_{\pm} x\right)
With r=\frac{V\lambda \pm c\sqrt{\lambda^2}}{V^2-c^2}
Now you can distinguish three cases...

How and what expression do you get for the separation constant. I know that usually this is done by the boundary conditions, but I don't see how that works here, because application of the boundary conditions imply a trivial solution .
