My mother needs closed captions, and I'm thinking of upgrading her from a Series 1 Tivo to the Comcast DVR.
The Tivo box displays CC when fast forwarding at 2x. This is optimal behavior.
Does the Comcast DVR support closed captions on SD, and do they display when you fast-forward at 2x? Does the DVR box do the captions itself, or does it pass it through to the TV?
I understand HD CC is a whole different ballgame, will it be implemented eventually?
