Why is the volume on some of the Denver local channels so loud. It is annoying as you have to reduce the volume everytime you view these channels. Currently the channels are 8201-KCNC, 8203-KDVR and8205-KTVD and what is perplexing is that these loud channels will change from week to week. Is Dish doing something here? The OTA channels do not have this variation in volume.
