Could someone please tell me how many live transponders I should have on Sat. B(119). That is how many should be receiving some kind of signal ...... I currently have three, but sometimes a fourth one shows up..........should there always be four or should there be more than that??? Also, I read somewhere that Transponder 31 carries most of the HD content on Sat. B......do any of you know that to be true. Thanks alot.........
