1. A computer-readable memory having processor-executable instructions that, when executed by a processor, perform a method comprising:

  • receiving a request to start a new media stream from a media-stream presentation device on a media-stream network having one or more bandwidth-limiting chokepoints therein; and

    generating a start-up profile based on chokepoint bandwidth data that indicates the conditions under which a presentation device can start presenting the new media stream without underflowing, wherein the conditions provide a temporally based test for a succession of timeslots of whether the device has received enough data at each timeslot to avoid underflow if it begins playback at the timeslot.
