I am curious to how many people run there noise rejection on high? I normally run mine on low or medium on my 1222 but sometimes the image is so cluttered i contemplate switching to high. The only issue i have is that when i switch to high from medium or low my image seems to be in slow motion. Does anyone else recognize this on there units or is it just me. I understand the comp is working harder to filter out more clutter but it just seems liek a odd image to me...
