I am having problems with the audio volume settings when I change between an HD channel and a non-HD channel. I have tried various skins and am currently using YouVIX -Green (1920x1080). On an HD channel the volume settings on the receiver and my TV are both low and what I would say are 'normal'. However, when I change to a non-HD channel I have to increase both the receiver and TV volume levels substantially before hearing any audio. Conversely, when I change back I nearly shatter my ear drums before adjusting the volume levels back down! I have spent several hours trying various settings on my receiver and TV to get consistent volume levels when I change channels but without success. Any suggestions as to how to solve this issue would be greatly appreciated.
