My TiVo didn't even recognize that there was an episode of Desperate Housewives on tonight. I have a season pass for all episodes (not just new ones) and it didn't even show up in the Record History as not recorded. I wonder if my TiVo was just being flakey or Comcast had a scheduling blip.

[Edit]: Interestingly, it was because of how the episode was named. It was a clip show, so I guess I didn't miss much. There is a discussion here.
