I recently activated a HR-21 700 receiver and i get all sd channels but no Hd channels. My setup is two Hr-21 coming from slimline-3s (SWM) going through a 4 way splitter to the receivers. The other Hr-21 receives HD and Sd fine, when i check the sat signals the one receiver sees the 101, 99 , 103 and swm ok, but the other receiver only shows seeing the 101 and swm. I have switched the cabling between the two and have done several reboots to the receiver. It has been about 48 hours since i reactivated. Any ideas?
