Hi Joris ...
I can only speak for myself in saying that I'm not expecting you guys to fix Spout issues. I'm only sharing my own experiences that other Resolume users might find useful as we work out the pattern of how Resolume and Spout interact, and sharing tips on getting it up and running.
However, it's not always clear to us end users what is a Spout issue and what's a Resolume issue, since getting the two to work together involves both pieces of software. All we see is the end results, but we don't have source code level knowledge to be able to say why "A + B = not working".
By the way I have done and will continue to leave messages on the Spout forum
Native Spout support - that would be something.
