The next morning i had to turn off the dish signle to wath the dtv signle, which is making my twin screen feature useless. I can't figure out why it worked one day and not the next. The dish feed seems to be going both to channel 4 and input 1. Changing the dish to channel 3 doesn't help. Any suggestions?
