    I have a WinXP system, and have downloaded an ISO file and
    successfully burned it to a DVD-r. It contains music videos. I'd like
    to create AVI, WMV, and/or MP4 files out of one or two of those
    videos.

    What is the best way to extract just a video or two from either the
    ISO file or from the DVD-r?

    I have TMPGenc, Windows Movie Maker, and a few other tools, but am not
    clear on whether even though the ISO file already resides on my
    computer, is it still necessary to input the contents of the DVD-r by
    means of TMPGenc? Or is there a program that will let me view the ISO
    file and then slice just a selected portion out and save it as an AVI,
    WMV, and/or MP4 file?

    Thanks for all suggestions.

  2. I'm no expert, but if I've understood you correctly, I'd work with the
    DVD files, i.e. the VOB files in the VIDEO_TS folder on your DVD-R or
    transferred to your HD. Using your preferred choice of editor.

    In my case I'd probably use VideoRedo or Womble MPEG Wizard. Assuming
    by 'TMPGEnc' you mean something like my TMPGEnc 3.0 Xpress, that's
    another alternative. Under its Set Source tab, you'd use "Add a source
    from a DVD-Video". (BTW, I encountered a restriction re Dolby in my
    use of TMPGEnc 3.0 Xpress which I enquired about in the thread 'Re:
    DVD file to Mpeg/WMA file conversion' two days ago.)

    In VideoRedo it sounds like you'd want to open the whole VIDEO_TS
    folder. You'd get the message
    'More than one file is being opened
    Press "Combine" to group the selected files into one large editable
    file.
    Press "Join" to sort the file list and add each file to the joiner.'

    After pressing Combine you'd then use the Cut and/or Trim tools to
    save whatever chunks you wanted.

    If you *did* want to work directly with the ISO, you could open the
    DVD in a program called IsoBuster
    http://www.isobuster.com/isobuster.php. This would display its
    structure, e.g. like this for a 4 track DVD I made recently:
    Name Size
    VIDEO_TS.BUP 16.00 KB
    VIDEO_TS.IFO 16.00 KB
    VIDEO_TS.VOB 12.81 MB
    VTS_01_0.BUP 12.00 KB
    VTS_01_0.IFO 12.00 KB
    VTS_01_1.VOB 171.23 MB <-- These
    VTS_02_0.BUP 12.00 KB
    VTS_02_0.IFO 12.00 KB
    VTS_02_1.VOB 115.90 MB <-- are
    VTS_03_0.BUP 12.00 KB
    VTS_03_0.IFO 12.00 KB
    VTS_03_1.VOB 195.03 MB <-- the individual
    VTS_04_0.BUP 14.00 KB
    VTS_04_0.IFO 14.00 KB
    VTS_04_1.VOB 300.50 MB <- tracks

    R-clicking a VOB and choosing Extract would save that VOB file in a
    location of your choice. (But I'm not clear what advantage that has
    over simply copying that VOB from the DVD-r directly? Maybe someone
    can tell me please? Is it perhaps a copyright/decrypting issue?)

    As far as I know, and I haven't conducted tests, there's no real
    difference in this case between using IsoBuster and a copy operation
    in Windows Explorer. After all, IsoBuster is not a decrypter, so
    circumvention of copy protection measures isn't an issue here.

    I just think that using IsoBuster is sexier than using Windows
    Explorer, don't you? :) I mean, if you were doing this commercially
    and not as a hobbyist, and you were designing a graphic for a
    DVD-Video disc menu, would you rather the client saw you working in
    Adobe Photoshop with a thousand different plug-ins -- or in Windows
    Paint?

    You know what I mean?

    Besides, IsoBuster is useful for checking disc integrity, checking for
    surface errors and readability, as well as determining exactly which
    file systems happen to be on a given disc.

  4. Thanks Frank, understood. I'd thought maybe it was capable of
    decrypting. Installed and paid for it a year or so ago, when I was
    having trouble loading many DVDs (probably due, I now think, to my
    hardware, which I've since replaced).

    Yes, I seem to recall a period of time there where you were getting
    bad burns. Glad that you got that resolved.
