Creating Windows dvd with the problem of the "invalid class string".

When you try to burn a file to a dvd using windows dvd creation, I received a message 'tring class not valid' when burning, and the disc has been ejected. What does the message mean? How to fix?

Hi KEVINQUACH,

1. When you have the startup problem?

2. you remember to make changes to the computer before this problem?

3 - is this happen when you try to burn any type of particular file?

You can check out the following link and try the steps suggested by Aziz N Support Engineer on December 2, 2009, and check if this may help.

  • Failed to create the DVD__Invalid class string

    This happens in Windows DVD maker and has just started a few days ago, I can't think of any modification of the software just before that, I installed the recommended Codec pack but it was a few weeks ago

    The "invalid class string" problem: it can be solved by repairing the DirectShow filters in the system. Some guys do it manually by editing the registry. But there is a simpler solution: "Codec Tweak Tool" oder "Filmerit. (The first is one of the last and can be used with Windows 7 without problem).

  • creating Windows dvd burning only the aspect 4:3, even when set to 16:9 ratio.

    Burns maker Windows dvd only the aspect ratio 4:3, even when the value 16:9.was ok in vista, but not the case in windows 7 too movie maker in windows 7 is garbage.this pure direct essential bundle is rubbish.why should set us up with that? I bet that there is no answer. tried to download older versions of movie maker work. but you get directed to this essential live bundle .any way this isn't the end of the world.as, I did a few dvd place pods...

    Always the same question on 8 January 2015. Windows Movie Maker produces video files in 16 / 9, but Windows DVD Maker that requires to 4:3 when burning a DVD, regardless of the settings.

    Again, I tried severale time and again on April 24, 2015, the ratio has to be 4:3!

    Too bad because I like the creation of DVD menu.

    I found the solution... very simple and it will work every time. before you burn the DVD with windows DVD creation, make sure you 'exit' your video to mpeg2 format, no matter what software you use to edit your videos, make sure you "output" your finished video in MPEG2 before burning with windows DVD maker

    MPEG2 is a DVD format that windows DVD maker recognizes and so it will burn your video ratio 16.9 this video will play on any DVD player. AVI WMV formats won't work even if you copy with movie maker then MPEG2... This is the key ~ MPEG2 ~ that's the secret.

    Unfortunately, Movie Maker stores projects only as MPEG-4 (.mp4) or Windows Media Video (.wmv).

    If your solution is another problem. We should convert mp4 or wmv in MPEG-2, how?

    Why Windows has no simple and direct way to burn DVD screen wide ratio?

    never had a disc of windows vista with the new laptop and no option to make a recovery disk, and I need to format my laptop to factory / clean, help!

    How to get Vista recovery Media and/or to use the Vista recovery Partition on your computer.

    There is no Vista free download legal available.

    Contact your computer manufacturer and ask them to send a recovery disk/s Vista set.

    Normally, they do this for a cost of $ small.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    In addition, ask them if you have a recovery Partition on your computer/laptop to restore it to factory settings.

    See if a manual provided with the computer or go to the manufacturer's website, email or you can call for information on how to make a recovery.

    Normally, you have to press F10 or F11 at startup to start the recovery process...

    Another way I've seen on some models is press F8 and go to a list of startup options, and launch a recovery of standards of plant with it, by selecting the repair option.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Ask them if you can also make recovery disk/s for the recovery Partition in case of a system Crash or hard drive failure.

    They will tell you how to do this.

    Every computer manufacturer has their way of doing recovery disk/s.

    ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

    Or borrow a good Microsoft Vista DVD (not Dell, HP, etc).
    A good Vista DVD contains all versions of Vista.
    The product key determines which version of Vista is installed.

    There are 2 disks of Vista: one for 32-bit operating system, and one for 64-bit operating system.

    If install a cleaning is required with a good DVD of Vista (not HP, Dell recovery disks):

    Go to your Bios/Setup, or the Boot Menu at startup and change the Boot order to make the DVD/CD drive 1st in the boot order, then reboot with the disk in the drive.

    At the startup/power on you should see at the bottom of the screen either F2 or DELETE, go to Setup/Bios or F12 for the Boot Menu

  • Have two old CD/DVD with the old movies of family 8mm on them.  When I try toopen them I get a statement that ' cannot they in format Samsung "suggestions?

    Have two old CD/DVD with the old movies of family 8mm on them.  When I try toopen them I get a statement that ' cannot they in format Samsung "suggestions?

    that is a difficult question. Try VLC to see if it will open to them. Usually when the disc appears on the desktop, if you click on it and let go, then press the clover sheet and I (get info command), you should be able to choose which application/program can open them. I have not already heard talk of the "samsung" format, I know there is a stranger there (lie format MTS from Sony). Regarding the conversion of them, maybe MPEG streamclip or hand brake? worst case scenario, you may need to spend some money to buy a video conversion app/program

    Sorry I can't help you more

  • I have a project in iMovie HD6 and want export to Final Cut Pro.  I see that it is not possible from the previous questions, but is it possible that I could maybe create a dvd of the iMovie project and then who import in Final Cut?

    I have a project in iMovie HD6 and want export to Final Cut Pro.  I see that it is not possible from the previous questions, but is it possible that I could maybe create a dvd of the iMovie project and then who import in Final Cut?  I just want to make a new trailer for the project.

    What you suggest is possible but it takes software and third-party quality loss.

    Instead, export a QuickTIme movie. If you have a choice of codecs, choose Apple Intermediate Codec. You can save it where you want it-maybe in the movies.

    Then import the movie into FCP as a clip.

    Good luck.

  • Captivate 8: PDF export created a file with the extension PDF... but it's actually a video. Shouldn't it exported slides as appropriate PDF document?

    In Adobe Captivate, there is a 'PDF export' checkbox when you publish your project.

    He checked the box, and the publication of project created a file with the extension PDF... but it's actually a video. Shouldn't it exported slides as appropriate PDF document?

    No, it was published in an interactive PDF, has always been the case. It's another way to publish the video, that does not need to deploy it to an LMS or a Web server, you can send the PDF file. However, since Flash player is is more integrated in later versions of the Adobe Reader software, the user is to install it.
