CUDA encoding not working?

[Bendit]

The problem is not about the optical drive speed. The problem is CUDA seem to not work and/or ripping DVDs is now really slow.

Additionally when falling back to CPU, I have noticed that the contrast is wrong (too bright).

Can we have some news about this issue? I have paid for several dvdfab licenses and currently it's pretty much totally messed up for me. ANY NEWS PLEASE??? Thanks.
