I really haven't experienced this static with my set-up, but from an audio engineering point of view your descriptions sound like something is overloading the system at some point. Since the above post pointed out the issue in a system without a 950, it's possible the distortion exists on the software side of the equation, i.e. your cds and/or your dvds. It's also possible to assume that since these system are possible upgrades to your previous sound systems, you're now hearing these instances of distortion for the first time. This is just my opinion upon reading the above posts. If your problem is traceable to a hardware solution, then please ignore.

One more thing, I think a lot of these occurences of distortion on CDs and DVDs are completely related to the trend of having the highest possible level on their release. If this continues, I think there will be more times where people experience these problems. Again, just my 2 cents on the state of the music and film industry.
