1. A computer-implemented method, comprising:

  • identifying a plurality of audio/video stream pairs that may be selected for playback subsequent to a currently playing audio/video stream pair;

    for each audio/video stream pair included in the plurality of audio/video stream pairs, computing a probability that the audio/video stream pair will be selected next for playback based on a predicted rating of the audio/video stream pair;

    based on the probabilities, selecting a first audio/video stream pair and a second audio/video stream pair for pre-buffering, wherein a first probability reflecting that the first audio/video stream pair will be selected next for playback is greater than a second probability reflecting that the second audio/video stream pair will be selected next for playback; and

    pre-buffering, in a content buffer, at least a portion of the first audio/video stream pair based on a first set of rates, and at least a portion of the second audio/video stream pair based on a second set of rates,wherein the first set of rates at which the at least a portion of the first audio/video stream pair is pre-buffered in the content buffer are based on the first probability, and the second set of rates at which the at least a portion of the second audio/video stream pair is pre-buffered in the content buffer are based on the second probability, andwherein each of the first set of rates is greater than the second set of rates.
