Hello, I have the vip 722 dvr and when I am watching recorded movies from premium channels the volume is constantly going up and down depending on what is going on in the movie. Sometimes music comes on and it goes way up or action scenes come on and BAM!!!!! I am constantly having to raise and lower the volume I have tried different settings on the box IE: pcm only vs dolby ect. also changed from line in to rf. I have heard of devices that will automatically adjust the volume IE: when commercials come on. Are there any that work standalone or only ones that come in a receiver? BTW My 722 is hooked up to a onkyo 7.1 receiver via the 722's optical out.
