DVD Size Reduction on File Created by TMPGEnc DVD Author using DVD Shrink Error

    Good afternoon again group.

    I added 6.7 GB of my own MPEGs to a TMPGEnc DVD Author project and
    built a DVD folder. I tried to use DVD Shrink on that folder with no
    success, so I could fit the 6.7 GBs on one ?DVD5? 4.7 GB disk. That
    did not work. BTW, I used the same MPEGs but less of them on a 4.7 GB
    project and they worked, so I know there is no problem with the files.

    I then created an .iso with TMPGEnc, but when I used DVD Shrink I got
    an error from DVD Shrink telling me about a navigation error in a
    dialog box. Any thoughts?

    Any thoughts on an alternate method of shrinking the dvd I create. I
    want to create DVDs in the 8 GB range and them make them smaller to fit
    on one 4.7 GB disc.

    I posted similar thoughts at an earlier time, but I like this idea of
    the above method better.

    Thank you.

    Do your adjusting when you create the Mpgs to begin with. Use a bitrate
    calucator to determine the bitrate you would need to put X minutes onto
    a dvd and create Mpg files using those settings. A good rendering app
    should do a better job of it than having DVDshrink hack up the files.

    Why should DVDShrink give worse results? An encoder throws away
    information in order to fit the bitrate requirements, which is a
    quantizer thing, and DVDShrink just does the same.

    Anyway, DVDLab can also be used to author and shrink at the same time.

    The point was, why drag it over to dvdshrink when it was in an
    application specifically designed to do exactly that to begin with.

    Going back and re-encoding these files isn't an option. Plus I may
    keep them as a higher quality too. I still don't understand why I'd
    get the following error: "Invalid DVD Navigation Structure".

    Thanks again.
