when i goto point dish and look at the signal strength of lets say 119 on tuner 2 the bar shows green and i have a number of 113. now i switch to 110 and it does not show any signal. i also don't have the tone for signal strength. if i switch transponders to 1 for both 110 and 119 it will show me good signal for both 110 and 119. but after i exit the menu and go back to viewing tv the receiver reselects transponder 7 for both. any idea whats going on. sorry if this doesn't seen clear but its difficult to explain. It's just not consistent with the way it operates. sometimes i can go the the point dish screen and it works right and other times it doesn't. the picture will freeze at times and i've also had the receiver reboot on me while recording an event. Is anyone else experiencing the same inconsistent operation from the 942?
