Hey guys, Can someone put that into something I can understand?! I am considering a new receiver and based on your feedback (thanks!) I am now considering stepping up to get CVS capabilities. I have an x-box, dvd player, and Toshiba widescreen HDTV. I will be running Polk RM6005's. I'm not sure what the term means or what it's practical purpose is. If you can help, that will aid my decision making process. Thanks!
