Advertisements I always thought that the comcast deal of porting TiVo software was the best thing since sliced bread. Then today I started thinking......What if the comcast deal entices standalone TiVo users over to ComcasTiVo? Tivo would go from getting say $13 for that user, to getting something like $1 as a ComcasTiVo user. That means that ComcasTiVo needs to sign some 13+ users for each standalone user that switches. Of course there is additional revenue to be had from advertising since you have a larger sub base. Anyone else concerned about this?
