In response to a request initiated by a user at a user terminal, selected entertainment programming content, when broadcast, is recorded at a location remote from the user terminal. The request is communicated through a communications network, e.g., cable TV network, which is also used for transmission of entertainment programming content to user terminals. The recorded programming content is stored in a storage space at the remote location, which is allocated to the user terminal. In response to a review request from the user terminal, the recorded programming content is retrieved from the storage space allocated thereto, and transmitted to the user terminal through the communications network. The presentation of the recorded programming content may be manipulated by the user to perform rewinding, pausing and fast-forwarding thereon.
