Hi Duane - What version of the colordmd firmware is running? You may need to upgrade. I would also reach out to Randy and the folks at colordmd. They are great at helping resolve issues. I had the same flickering issue when I put a colordmd in my Whitewater a couple years ago. I sent a video to Randy to show him exactly what the flickering was and he ended up creating version 3.1 of the firmware which corrected the issue. If you go to the colordmd site, you will see version 3.1 of the firmware which addresses the flickering issues. I'm assuming that your colordmd is not a chroma (newer) version. Don't worry... you will get it fixed.
