Where does program guide come from using a CC?

Using a CC, doesn't the Guide (program) data still come from TiVo, not the MSO?

TWC is claiming they provide the data along with a $2.80 charge even if you don't have their DVR.



I did find this, but it is another operator;

The guide data is downloaded from the TiVo service by the DVR. Guide data also contains the channel number and call sign. In addition, it has program listings for each channel and descriptions of every show.
