A receiver receives media for playing out using a presentation element of the receiver can make requests and wait for responses, but can also cancel requests, possibly reissuing new requests, to improve a user experience taking into account network and other conditions. The receiver can select a playback rate and make requests at that playback rate, monitor a presentation buffer that stores media data to be consumed by a presentation element, store an indication of a buffer level corresponding to how much of the presentation buffer is occupied by the media data that is received and not yet consumed by the presentation element, maintain a state of an issued request for downloading a selected first chunk of media data, and when an issued request is outstanding, determine, based on network conditions and the state of the issued request, whether to continue the request or cancel the request.
