        The need to reduce the huge demand for bandwidth of
        video-on-demand services has led to the consideration of
        techniques based on multicast for the deployment of such
        services on a large scale. Interactiveness, a desirable
        feature of video services, includes the capacity to per form
        VCR operations. Whenever a viewer issues a VCR operation,
        his/her video stream be comes unsynchronized with that of
        his/her multicast group. The present paper introduces a novel
        approach for determining the number of video channels needed
        to support such interac tiveness. Moreover, it investigates
        the performance of interactive systems with a reserved pool of
        channels for the support of VCR operations. Systems with
        batching and with both batching and piggybacking are analysed.
