    The Sony HX900 DVD Recorder can record at 15 Mbps is there any real
    advantage of recording at this speed to the hard drive?

    I can't see any difference in a video recorded in this quality and
    that of 10Mbps which is the one hour quality mode.

    Maybe the 15 Mbps video quality is used to minimize the loss when
    copying from the hard drive to a DVD disk and converting the copied
    video to a lower quality such as SP.
    I tried copying between the hard drive and the DVD disc several times
    to create a 4th generation copy of the video (that had been recorded
    in SP and could only see a small loss in picture quality. The quality
    was still better than LP quality (3 hour mode).

    There may also be an advantage using the 15 Mbps mode when copying a
    DV camcorder tape to the hard drive. Does anyone know what the video
    rate is for a a video that has been copied to the hard drive on a
    computer as an AVI file (unrendered)?
