Ok, I found the problem, it was the Arcsoft DTSdecoderdll.dll. Once that was out of the system, it works with one caveat. In Processing, the upsampling 44.1k must be set, it won't allow 88.2. Is there a way for MC to force 44.1k on .dts files? I want the 88.2 on my standard CD sourced files. It seems like this would be an easy modification, is that possible on the next build or something? That would be great, because I really want to be able to seamlessly integrate my library without worrying about the source. Pretty please? Thanks!!!
