The Chad sent me this screenshot a couple days back, showing banner ads on the DVR guide from Comcast:
Looks like people are noticing it in other places as well. I can't say I'm surprised, as I remember having a AT&T cable box in 2000 that used to be covered in TV Guide ads on both the guide section and when displaying show information. Still, seems silly to do this to owners, years after they've been using the guide free (not to mention there's already a $9.95 monthly rental fee for the box).
Did I mention I can't wait until I get rid of this box and buy a Series 3 TiVo? Please TiVo, release it before the Fall season really gets started! [thanks Chad and Chris]
