Spoke with Sherwood support, very pleasant and knowledgable. Feels the HDMI board and supply for inputs 2,3,4 are a problem, I switched the dvd to 1 perfect. He explained that hdmi board input 1 is a separate board and supply whereas input 2,3,4 share the same board and supply. He said to send it for an exchange where I got it brand new 2 days ago but that is not an option as they will not do an exchange only refund and for me to send it in and pay for shipping, they said they would pay shipping if they found something wrong but the impression I got they would find nothing wrong even if it is. Wanted an exchange not a refund. They blamed everything on the cables even though I used the same dvd and cables as on my other 972 to test. The reason I feel and support did as now the satellite on 2, 3, or 4 is acting weird. Very unhappy with the dealers response.
