Thanks for the question. Usually on BD movies or DVDs, you would not want to use the Auto Motion Plus (the setting that affects the blur and judder) feature, since these formats offer their own Hz that should not be changed (Blu-Ray in specific outputs at 24Hz, which is a feature of this format. AMP will process that signal up to 120Hz on your unit, which may result in some picture quality issues. AMP was designed to take a 60Hz signal and double it to 120Hz). With the cable signal, please make sure that the set top box is receiving and outputting a strong enough signal in order for AMP to process it. Again, as with BDs, a week cable signal can cause AMP to not work properly. I would suggest deactivating Auto Motion Plus to see if that alleviates the issue. If it does not please feel free to contact our service department at http://www.samsung.com/us/support/o...
