I signed up for Comcast basic cable a few years ago because I was hosting a Superbowl party. I signed up in person at an xfinity store because I didn't want to wait around for shipping. Right after I told the dude at the desk I had a brand new HD TV that I was eager to watch the Superbowl on, he tried to send me home with a cable box that only had one output: (standard definition, analog) coax. I don't even know why they would still offer such a thing, but I had to fight with them to get a box that output HDMI.
