Were the scene files created specifically for that exact copy of the camera? If the scene files are from another camera or "generic" scene files written for HDX-900's, that could be the problem. Remember each camera is unique. Generic scene files will usually get two same model cameras very close and even so close you can't see any difference with the naked eye, but they might not unless adjustments are made for each specific, individual camera. Or it could be the scene files you are using were created by someone that just cranked the reds. I used to shoot with a guy who had his colors set to "cartoon". Especially his reds. He thought it looked great, but he was wrong.
