My current setup consists of one HR34 & two HR24 HD DVRs for a total of 9 tuners. I am using the SWM LNB (ODU) integrated with the dish that supports 8 tuners. I have one of the HR24s configured in single tuner mode with no issues. My question is that if I add an AM21 to the HR24 in single tuner mode will I be able to record one channel off of the AM21 (OTA) and one off the satellite at the same time? Or watch one channel on the AM21 tuner (OTA) and record one of the satellite tuner at the same time?
