output videos faster are faster than mpeg original files

[tayrot]

Hello, I am a beginner in work with dvd authoring, my problem is:

I am creating a image dvd (using dvdauthor) with some mpg files, and when i try to see the burned dvd in my dvd player the videos/audio are faster than the original files (I tried to see in 3 different dvd players but the result is the same ) ! This not happen using a "dvd player"in my computer (for instance PowerDVD)....

I am doing the following:

//demultiplexing the files
mpgtx -f -d c:\menu1.mpg -b MENU
mpgtx -f -d c:\maico1.mpg -b MAICO

// multiplexing to DVD NAV
mplex -f 8 -S 0 -M -V -o MENU.MPG MENU-0.m1v MENU-0.mp2
mplex -f 8 -S 0 -M -V -o MAICO.MPG MAICO-0.m2v MAICO-0.mp2

and after that:
// Creating the dvd image
dvdauthor -o DVDIMAGE -x dvd2.xml

where dvd2.xml is:


<dvdauthor>
<vmgm>
<menus>
<pgc>
<button>jump title 1;</button>
<vob file="menu.mpg" pause="inf" />
</pgc>
</menus>
</vmgm>
<titleset>
<titles>
<pgc>
<post>call vmgm menu 1;</post>
<vob file="maico.mpg" />
</pgc>
</titles>
</titleset>
</dvdauthor>

Any help thanks in advance!

Maybe you should specify the video norm (PAL/NTSC).
I'm not sure about the default in dvdauthor (if any).
The framerate (and therefore 'speed' which is dependent on the PAL/NTSC setting) is specified in the ifo files as well as in the vobs. Now it could happen, that these two are not the same (you can check the value in the ifos with ifoedit, and in the vobs with my chaptereditor (chapeditgfd) or any software with suitable mpeg2 infos).

I think that soft players like PowerDVD will use the framerate from the vob files and even change it if there are different ones within the vob (not allowed for DVDs!), whereas SA dvd players might simply use the specified rate from the ifo.

BTW: You can use one of the GUIs (dvdauthorgui, dvdstyler or gfd) to check if you get the same error. Otherwise check the syntax of the author.xml file(s) generated by these GUIs compared with yours.

Thanks for your help Borax,
I will try to use dvdstyle and gui to compare the author.xml and the results!
