How to use DTV R10 w/Comcast Cable?

[georsk]

I have a DirectTV R10 unit. Don't have DirectTV any more, instead have Comcast cable.
Question - how can i connect my R10 Tivo unit to work with Comcast cable?
Thanks for any help you can offer on this question.

You can't. You would have to get a SA Tivo to work with it.

DirecTV DVRs cannot record any analog video sources, like cable TV or cable boxes. They can only record DirecTV's digitized satellite data stream.
