wmoyes writes "Back in September I ran into a Best Buy store to buy a Samsung BD-P2550 Blu-ray player. I didn't give the clerk my name, telephone number, or address, just my debit card. The player has sat happily in my living room without ever being networked or registered. Today I was shocked to find a package waiting for me at home from Best Buy — inside was a firmware update CD for the player. I used to think Windows Update was scary, but Samsung's update service tracked me to my house using the mag stripe from my bank card. Has this happened to any other Blu-ray owners?" Or is there a simpler explanation?
