so whats with the diffrence in input vs output db? did you turn output down or something? if not then wtf is going on?
oh and btw, that comment of andys about rotateing a jpeg sounds more like a bug in the software then something with the image compression as rotateing a image is just reading the same image data into a diffrent reference (vertical becomeing horisontal and left becomeing right and so on). altering speed while keeping pitch sounds more like stretching a image horisontaly while keeping the vertical stable...
