Comcast now lets you watch cable on your Roku

Comcast is letting you ditch your cable box for a Roku.You can finally dump your cable box thanks to a surprising source: your cable company.

The assist comes from Comcast (CMCSA), which on Tuesday launched an app for Roku streaming-media players and Roku-enabled TVs that duplicates just about all of the functions normally found on the company’s cable boxes ranging from on-demand video to its cloud DVR service.

The news is both overdue — the underlying streaming-to-apps technology has been in tests by cable operators since at least 2012 — and timely, since Tuesday also formally ends the Federal Communications Commission’s attempt to require subscription-TV providers to ship apps that would allow fee-free viewing of their channel bundles.

Unfortunately, other TV providers don’t seem interested in following its example — and although the app is free, the actual savings look like they’ll turn out to be less than you’d hope.

Comcast’s new app deal: warning, math required

The new, free-to-download Xfinity Beta app isn’t Comcast’s only offering that allows you to stream cable. It is, however, the first that lets you stream your service on an actual TV instead of forcing you to use a smartphone or tablet. The Philadelphia company’s iPad app, though, still blocks AirPlay output to an Apple TV.

Like the cable provider’s others apps, the Xfinity offering doesn’t rely on Comcast’s traditional TV cable lines. Instead, it streams channels over a separate portion of your broadband internet connection to ensure buffering-free viewing.

The Roku app will work on all Roku TVs and devices shipped in the last couple of years including the Roku Express, Roku Express+, Roku Streaming Stick, Roku Premiere, Roku Premiere+, Roku Ultra, Roku 2, Roku 3 and Roku 4.

You get the same interactive programming grid found on Comcast’s X1 cable boxes, including access to on-demand video and the ability to record and watch shows using its cloud DVR service. All you give up in terms of your TV-watching experience, according to Comcast, is the voice control capabilities available through the X1 remote.

But while the app is free, you won’t save as much as you’d think. Comcast normally refunds $2.50 a month if you use your own cable box, but it won’t offer that during the beta-test period. Its usual $10 monthly fee for cloud DVR service will still apply too.

After the beta trial, though, you will start collecting that $2.50 monthly credit. What if you have a second screen? You’ll get a second $2.50 credit for using the app instead of a box, and Comcast’s FAQ says you’ll dodge the provider’s $9.95 monthly fee for a second outlet.
