So, currently with my old receivers, I'm on the SWM system. I haven't had to upgrade a receiver in quite some time so sorry for my ignorance here. Since I may get the HR44 (which from my understanding is a receiver that can be used for the Genie setup), I wanted to ensure that, just because I was getting the HR44, I didn't have to start upgrading to the Genie system and that, this new receiver would work well in my old setup just as my older one did (and as my other older ones do).
FYI: I chatted with Directv and they tried their hardest to drop ship me a new receiver without a tech (they said they don't do HR22's anymore so most likely, it'll be a new one, like the HR44). However, after an hour of trying with multiple different people and departments, they couldn't get around the Tech coming, which they said he happy just to drop off the receiver if I tell them to. However, as mentioned, I was able to do a drop ship and just pay for shipping ($19.95)
Also, thank you all for your help and advice in all of this.
