The HR24 can be used with either a multiswitch dish or SWM dish and we used it to upgrade first the RV to SWM then later at home using only this receiver.
Then with SWM we now have the HR44 which is SWM only and we don't have a Genie Client receiver. What we like is the ability to record 5 channels at once. We very rarely watch live shows and instead watch a recorded show and skip over the commercials. Plus we have recorded shows waiting even if we're in trees. We had a month of overlap with both the HR24 and HR44 both on SWM and found it interesting that we could then record/watch 7 channels.
The transition from home to RV is seamless - plug and play. All settings, recordings, etc are the same. One TV is 720 and one 1080. Since both are HDMI the HR44 detects this and automatically changes the resolution.
