I installed a dmx741 on my 10ft dish with a coolsat 5000 and was using a uniden box just to move it. I purchased a vbox-x and hooked it up and now it appears that i have lost audio on some of the channels on 99w. Do I need to hook up something different or change some settings? It appears that I have lost audio on some of the other sat's as well. Not all channels just kinda intermittent. Is this common since i am going thru the coax with the vbox that it is dropping some of the the audio signals?
