Here's the deal: My 3 week old HR20 was getting flakier and flakier so I decided it was clearly defective and called the distributor I got it from (Value Electronics) for a replacement. (I considered getting the replacement through DirecTV, but thought going through Value Electronics would be more painless.) They sent me a new box, from which they had specifically removed the access card (told me to use the one from the defective receiver). They sent with it a return label that will return the old one to "DSI", the wholesaler from whom Value Electronics apparently got it. I connected up the new box, with old access card installed and called DirecTV to activate it. The CSR was quite friendly but he thrashed for quite some time to get the new unit activated. He clearly wasn't the most competent CSR there. He repeatedly apologized for all the trouble he was having and even once joked, "I'm glad my supervisor isn't looking over my shoulder, I'm kind of screwing this up!" Anyway, he finally got it activated. I checked several channels and everything looks fine. Now here's the part that worries me a bit: When I check my account profile on DirecTV's web site, the serial number for the old HR20, that I will be returning to the wholesaler, DSI, tomorrow is still showing on the web site. This is simply the serial number on the bottom of the unit, not any sort of electronic number. The CSR must have gotten the receiver ID and access card ID right (eventually) or the unit wouldn't be working. My new HR20 is working great (huge improvement over my flaky old unit ), but I wonder if some bookkeeping problem will arise when the defective unit with the serial number their computer shows me as still having installed shows up as a return. Should I call DirecTV and let them know that the serial number showing under my profile on the web doesn't match the one on my box, or should I simply keep my big yap shut since everything is working fine? I'd hate to open my mouth when everythings fine, only to open a can of worms that would disrupt my service! In other words: If it ain't busted, don't fix it. What do you folks think? Thanks.
