A client may, for example, initiate presentation of the content item in a hybrid stream mode in which both a client stream and a content provider stream are combined to form a resulting hybrid stream for presentation. The client may then, at some point during presentation of the content item, detect that the content provider stream has become unavailable. In response to such a determination, the client may continue to present the content item in a client stream mode, in which the client stream is used for presentation of the content item without use of the content provider stream.
