is at least 1 cable box required?

Hi,

I have the choice double play (Internet & TV), which includeds basic limited channels (about 30). I don't use the cable box at all as I can stream using either Roku or xfinity.com/stream. I tried returning my one and only cable box, and I lost the majority of my channels, leaving only about 7 channels available.

Is there a way I can keep my basic limited channels without having to rent a cable box?

Thanks,

Mike
