An integrated content delivery interface enables a user to access content from a multi-channel service provider (such as a cable television service) and over-the-top sources. The system displays a set of cable channels and over-the-top channels based on a combination of the user's subscription status for the various services, personalization criteria, and device type. The system may provide the user with a playlist of available videos for each channel. For videos from over-the-top sources, when a user selects the video for on-demand play the user's device will directly access the video as served by the over-the-top source. Before including any video in the playlist, the system will ensure that the video is available to the user based on subscription status and/or device type, and it will ensure that the over-the-top source serves the video in a format that is compatible with the user's device.
