PHILADELPHIA (CBS) — Comcast Corporation is starting a new service that aims to keep customers from straying to Netflix or other streaming video providers.

It’s called Xfinity Streampix.  For $5 per month (or included in some cable packages), Comcast says they’ll deliver movies and full, past seasons of small-screen shows to your TV, computer, iPhone, or iPad.

The cable giant says that it’s in addition to the tens of thousands of films and programs it offers “on demand.”

Xbox 360 and Android apps are coming, as well.

Earlier this month, Verizon announced a tie-up with Redbox to start its own streaming service.

Netflix costs a bit more than Comcast’s offering, but you don’t have to pay a cable bill to be a member.

Netflix and Hulu also are trying out some original, scripted series in a stab at adding value.
