A method and computing device for intelligently pre-buffering at access points in an adaptive or scalable stream to optimize trick-play support. The method receives a multimedia content stream from a multimedia content server as a series of segments, each segment including a key frame and corresponding to a predicted seek position in the multimedia content stream, where the multimedia content server delivers at least two versions of each segment, each version reconstructed from at least one encoded component of the multimedia content stream, the versions varying a characteristic of the multimedia content stream. The method determines a likelihood of receiving a seek request from a user to move from a current playout position to one of the predicted seek positions, and determines a size of a buffer for each version of each segment in the multimedia content stream based on the likelihood of receiving the seek request.
