Help on clips cutting from long mpeg-2 sequences

  1. Can you suggest me a tool (preferably freeware) for the cutting of clips
    from long mpeg-2 sequences?
    I need to extract clips of 25 minutes from a video of 1 hour.
    I tried it using TMPEG. It takes less than 15 minutes to do the job, but the
    audio of the resulting clip is affected by a defect of syncronization with
    the corresponding video (the audio is 2 or 3 seconds late with respect to
    the video). The defect is much more evident in the final part of the
    extracted clip (I verified that the defect is not present on the source
    file). Moreover, TMPEG is not very precise in the extraction, and the in and
    out cut points of the clip can differ of several frames from what you set.
    Adobe Premiere is far more precise: in and out cut points are exactly
    respected and video and audio are correctly syncronised. On the other side
    it takes 5 HOURS of execution to perform the extraction of a clip of 25
    minutes. Moreover, when I review the extracted clip I can notice some
    "jumps" in the video, not present in the original sequence (but I think
    that this defect is actually coming from an incorrect setting of the export
    parameters and it is not a "bug" of the application).
    However such long execution times make it impractical the use of Premiere
    for such appearently "easy" operations. So can you suggest me a different
    (simpler) tool, faster but reliable?
