Ok, a little over a day since I've had it and shes up and running well. Like others, my install went smoothly if only I could have talked to the good CSR first. Here's how it went.
Called the first time, went for Tech Support. Guy was real nice, was doing everything and then the "computer wouldnt let him" close out my ticket/install because I wasnt a technician. He put me on hold a couple times "calling other departments" to see what could be done because he needed some "codes" to finish it out. He comes back on the line to be the bearer of bad news and that I cant activate unless im a technician because "it would violate company policy and I cant break the rules" and "its a receiver worth $1500 so we have to make sure its professionally installed". I dont know about you guys, but if Sat installs are anything like IT, real "professionals" arent exactly as abundant as you might think. I complained and asked to speak with his manager, but denied. I tried to explain that it was bunk that I would pay for the platinum package and have a receiver sitting here for another month {cant be here on the 21st anymore for origional install date} and not be able to watch what im paying for. No luck.
Called again, asked for Programming. Got a fast talking lady who thought I was an installer - I told her i needed to activate a 622 receiver. She asked a bunch of questions like what channel was tv 2 on (60) was there a phone line plugged in, what the receiver ID was , etc. She even asked to confirm the customer's phone. I said "i think the guys number is ..."

Shortly after, it was activated....
Called a third time to confirm my platinum package. They said I could keep my existing receivers (811 and 322) and with the platinum + locals it would be ~$120 a month. I told them I was undecided about returning so soon. As soon as I hung up, all the channels came on.
Finished wiring up my OTA HD antenna coax, and not using an amplifier with the 811 it had a hard time picking up locals. I dont know why, I live 10 minutes from all the antennas where they rebroadcast from, and have line of sight. There's a huge antenna in my attic for UHF/VHF/FM. My TV picked them all up (sony XBR960) but the 811 sucked at best. I went in the 622's setup and scanned for OTA HD channels, it found
40. Holy cow! Sure enough, all the channels have 85% or better strength, change faster than on the 811, and IMO look better. Watched a little ice skating in HD.
Dont forget to change your reciever out of dual mode if you want to record a tv show on tv1 and watch something else on tv1 also. Since I have OTA antenna, I can record 3 HD shows at once and watch something pre-recorded
Overall, I'm pleased with the receiver so far. Component cables are indescriminate from my dvi-hdmi monster cable on the 811 (I know, monster - yech). Let me know if I can help answer any questions 
My setup as of right now:
