    I have many dvd;s with films from outer space. These films are 3 to 4 gb in
    duration. My question is can I somehow compress these films and store more
    then one or two on a dvd? If I zip them will I be able to accomplish my
    goal? if not is there some way to get several files on one dvd? My obvious
    problem is that I have several hundred dvd's and am running out of storage
    space. Thank you for any helpful input.

  2. If they're already in a compressed format, zipping them may very well
    make the product larger than what it was when you began. Try it, and
    compare pre- and post-zip file sizes.

  3. This Plextor product will enable up ten hours of DivX video on a DVD:

    All multimedia files are already compressed. The only way to
    make a movie file smaller is to RE-ENCODE it in a way that will
    take less MB -- BUT, in most cases, this will result in an obvious
    reduction in quality -- sometimes minor, sometimes major.
    For example, if you have a SVCD movie, it will, by its nature,
    be an MPG file(s) that take up 20 MB per minute. You could
    turn it into a VCD type of MPG, taking up 10 MB per minute,
    but the reduction in quality will be very obvious. If you converted the
    SVCD to an XviD-compressed AVI, it might end up at about
    13 MB per minute, with a more minor loss of quality, but, where
    the SVCD might have been playable on a most standalone
    DVD players, the AVI will not. If some/all the movies are
    already AVIs, compressed with XviD, DivX, or some other
    codec, they could be re-encoded at a lower bitrate, thus
    making the files smaller, but they will definitely look worse.

    In short, you can't get 10 lbs. of shit in a 5-lb. bag.

  5. You can if you compress it, but the results look like shit.

    thank you for that info. It is imperative that the quality of the film
    remain in its present form. I will not re-encode.

    Thank you.
    I did zip a trial version and managed to save about 20%
    of space. This will give me a temporary solution until I can come up with
    something better. I have a very large University that is willing to store
    them for me but my access will be severely hampered and that is not a good

    Have not had time to look into this but looks promising. Thank you

    Strange that you would start this thread and then comment several times
    without ever saying what the original format and bitrate is.

    How did you get films from outer space? Did the aliens bring them to you ?

    Now that is silly. Everyone knows you have to put up a really, really,
    really tall antenna, and use a DVD recorder.
