Took us a few trys with the iRV to figure out that problem. It also does it with the DVD surround sound (TV-Audio), especially make sure #3 is off when you are watching the HBO series, Deadwood! The language would shock a Sailor!
Our neighbors just bought a new Flagstaff and we went over to look at it, saw she had the iRV, told about 1, 2 & 3 - said the walk thru never mentioned that, she was grateful
