I have a mt2 ota module on my vip722 and continue getting random drop outs. It's not the signal because I can hook the very same cable to my hd tv and get no drop outs. Sometimes when I turn of a light the channel drops out,and sometimes it just drops for no apparent reason. So,question is...Should I replace the module or just stick with the drop outs. It's hard watching the recorded shows with these drop outs.( They pretty consistant)Live shows I can watch without the receiver. Are there known problems with the MT2?
