What program can turn VIDEO_TS hard disk files into .iso?

  1. Hi. I have encountered a sync problem when burning DVD files to DVD-R
    (DVD Video) with Nero. Now I find out Nero has known problems when
    burning DVD's. I read a good way to go is to create an image file and
    burn it with DVDDecrypter. My question is:

    What program can I use to convert VIDEO_TS files on my hard disk to

    I'll explain the process I am using below, for completeness.
    I am creating DVD's from recorded TV by the following steps:

    1) Record from analog cable on AverMedia M150 card with GB-PVR
    (excellent FREE PVR software)

    2) Edit .mpg file with Womble MPEG Video Wizard 2003 (excellent

    3) Author the DVD to hard disk with TMPGEnc DVD Author 1.6 (works

    4) Burn DVD with Nero (works like crap -- sync problems!)

  2. Actually I just remembered TMPGEnc DVD Author has a DVD writing tool
    built in. I am trying that now to burn a DVD. I can also create an ISO
    with that tool, and burn an ISO with that tool!
    I'll report what the result is.

    Have you got DVDshrink installed?

    You can load your VIDEO_TS folder etc into DVDshrink and back it up with no
    recompression and DVDshrink allows you to choose an ISO file as the output.

  4. Yes, I have that, thanks. Good to know.

    As for the TMPGEnc writing tools, it worked fine, but on that simple 1
    GB mpeg file so did Nero. I need to create another full disc worth of
    data, see that it doen't work in nero, and that it does in TMPGEnc (or

    You've got it, Nero.
    Hi David,

    It looks as if you've gotten some bad info. It would be practically
    impossible for any program to give you bad sync while burning a DVD
    from authored files on your hard drive. Burning a DVD is a straight
    digital copy of what is already in existence. You may get a bad burn
    from Nero, but if there is a sync problem with your DVD, it is because
    there is a sync problem with the authored files on your drive.

    Think about it, what you are saying is that when you mail a letter the
    Postal Service is causing spelling errors in your sealed up letters.
    The Postal Service may lose your letter, or mangle it, but any
    spelling errors were there before you mailed the letter. Any audio
    sync problems in your DVDs are already in the authored files.

    There are many places where audio sync issues can be generated.
    During capture from analog, during editing, during trans-coding,
    during authoring, etc. Burning is not one of them.

    You will need to annalize each step of your process to determine where
    the sync problems are occurring, and it may be happening at several
    places and you are not noticing it until the end.

    Each of your steps 1-3 are full of places where sync errors can occur.
    Step 4 is not one of them.

    Hope this helps.

  6. Excellent essay, Susan!

    It might be worth suggesting to the OP to play his VIDEO_TS folder
    with a software video player (both Windows Media Player and
    InterVideo WinDVD will do that on my computer).

    Then he will see directly - as I did just a day or two ago - that in
    fact the .vob's are already out of sysnch.

  7. It's funny, because I could have sworn I checked the VOBs for sync
    before burning, and they were OK. But Susan's saying not possible. I
    deleted the VOBs after burning, and before checking sync on the DVD's,
    so unfortunately I couldn't go back after burning and check the VOBs in
    this case. Thanks for your input on this. I'm glad Nero is not the

    Does anyone know why in another post someone wrote "Nero has known
    problems burning video"?

    Maybe because of the recording format. My desktop DVD recorder (I
    guess, all of them), records VOBs which are not the ordinary kind, as
    they authored "on the fly", and I need to demultiplex them twice in
    order to avoid desynch.

  9. What do you mean, "not the ordinary kind"? Is there some way of
    checking whether the VOB's on your hard disk are exactly what will be
    burned to DVD? How do you demultiplex and avoid desynch?

    I capture with a Pinnacle Movie Box 2.0 for the past 15 months or so.
    This encodes directly to mpeg-2.

    Dropped frames have always been the cause of my A/V sync problems.

    Tried the VideoRedo program last December. "Quick Fix" removes audio
    and video frames that cause "audio drift". This has fixed all of my
    problems so far. Program will report the number of audio and video
    frames corrected.

    This must be used before the the mpeg file is demuxed into elementary
    streams for inclusion in the VOB during the authoring process.

    There is a 30-day trialware ($50US) on the product. I purchased after
    21 days, great program.

  11. In my case I record from TV using an AverMedia 150 card and PVR
    software. Are you saying that even though the VOBs I create with the
    mpeg2 files are in synch on the computer, I should run them through
    VideoRedo before burning the VOBs or I may encounter out of sync on the
    DVDs? I would have thought out of sync problems would be apparent in
    the VOBs. Is that incorrect?

    Yes (and no).

    If the capture is out of sync, then the VOB's will be out of sync,
    either on the computer or burned to the DVD. The captured mpeg-2 will
    appear to be in-sync when played on the computer, but if one demuxes it
    into elementary mpv and mpa streams, remuxes it, then that remuxed file
    too will be out of sync.

    This is of course due to the mixing of the A/V frames in the captured
    mpeg file and the playback program resyncing the A/V constantly
    according to the mpeg time stamps. After demuxing, those relationships
    are lost. It is like having one rope comprised of two cords
    entertwined. If we take the rope apart, then we might find that one of
    the component cords is longer than the other. Putting the rope back
    together is possible, but it won't be intertwined exactly the same way.
    For DVD's, the component video and audio files must be of the same
    duration. Each runs on its own "clock". The player will sync the
    output according to their clocks, but if one clock is fast, then we
    will get the audio drift effect.

    Some of these problems are very small. I run through VR and it will
    either do (about 1/3 each):

    1) No corrections, meaning that no frames were dropped during the

    2) A small number of corrections, indicating that I may or may not
    visually or audibly see/hear the problem, until something just "doesn't
    seem quite right". I have several of those that I have done over the
    past 18 months (before hearing about VR), but have since dispensed with
    the original captured mpeg.

    3) A large number of corrections, that I would have caught by first
    going to the end of the mpeg and noticing visually/audibly.

    In any case, this one feature of VR is worth the fifty bucks to me.

    Most of the problems that I have encountered have been as a result of a
    bad recording, generally older VHS tapes, that have age or just
    manufacturing flaws in them. But these are generally the ones that I
    wish to keep.

    Anyway, I am very high on the product, and would recommend to anyone
    doing hardware mpeg captures to have this program as a post capture

    I used to cut up a captured mpeg file into smaller and smaller pieces
    to isolate the problem. VR saves hours of time. I discovered the
    program in December, so I am still infatuated with it. Very simple,
    and for me and other mpeg capture addicts, pure Video Voodoo :))

    I do not know exactly which is the difference, except that an authored
    DVD has .VOB, .IFO and .BUP files on the VIDEO_TS folder, but
    recordings from a desktop DVD recorder also have another folder
    (VIDEO_RM?) with the necessary information for the .VOBs in VIDEO_TS
    to be played adequately.

    If you rip the VOBs from a "regular" DVD to the harddrive, they play
    without desynchronization, but if you do the same with the VOBs from a
    desktop recorder, there is desynchronization.
    This way (it took me some time to find it, and it's cumbersome, pero
    it does work):

    1) I rip the rewritable DVD to the harddrive with DVDDecrypter in IFO
    mode, with demux Stream processing. One would expect to get a video
    file and an audio file, but actually it gives you an .m2v video file,
    and a .vob file. This .vob file has the audio, but also an empty video
    stream (a video stream at 0 kbps). If you try to play this .vob with
    MediaPlayer, it shall only play the audio, but you shall find that it
    seems to last twice as much as the video.

    2) Demux the empty-video .vob. It shall just give you an mpeg audio
    file (.mpa or .mp2, depending on the program you use to demux). And
    now this audio file does last as much as the video.

    3) Multiplex video and audio, and now you shall have a regular and
    well synchronized .mpg

    Now, when ripping the DVD, DvdDecrypter also gives you a "Stream
    Information...txt" file, which tells you about the audio offset. You
    should take this into account when muxing video and audio. I do that
    multiplexing with mpeg-vcr, which allows you to set the audio offset
    for the muxing (Tmgpenc, for instance, can well multiplex video and
    audio, but does not allow you to set the audio offset).
