Comcast is pushing PVRs so hard these days you'd think they were giving birth. It's kind of funny that they are using their website to remind people of one of the drawbacks of PVR ownership: they published Six Feet Under spoilers in their entertainment headlines (contains spoilers as of Aug 1, 2005. Obviously).
Imagine it. A customer has seen enough ads for the Comcast DVR that they decide to set it up to record Six Feet Under so they can watch it the following night. Meanwhile, they check out Comcast's site and have a major plot point ruined. Do you think they're going to be all that interested in time-shifting after that?
