Searching for help on this subject and found this post. I have the same card with a M12000. I don't just have pops though, mine actually plays fine for a seccond, and then slows way down and distorts for a seccond. Also, the problem only seems to exist for discs that contain a dolby digital as well as the DVD-A track. On discs that are purely DVD-A, I don't have any problems.
