I'm currently trying to make a dvd with 3 different videos, first with 16/9 aspect, second with 4/3 aspect and the third 16/9 aspect. There isn't many examples to show how to do this but so far I found from
http://forum.doom9.org/showthread.php?p=832921

which I did

Code:

<dvdauthor dest="DVD">
  <vmgm />
   <titleset>
     <titles>
       <video widescreen="nopanscan" aspect="16:9" />
          <pgc>
         <vob file="14.mpeg2" />
          </pgc>
     </titles>
   </titleset>
   <titleset>   
     <titles>
   <video widescreen="noletterbox" aspect="4:3" />
   <pgc>
    <vob file="test.mpeg2"/>
   </pgc>
     </titles>
   </titleset>
   <titleset>
     <titles>
   <video widescreen="nopanscan" aspect="16:9" />
   <pgc>
    <vob file="10.mpeg2"/>
   </pgc>
     </titles>
   </titleset>
 </dvdauthor>


I do this and then use this to make the iso
Code:

mkisofs -dvd-video -v -o DVD.iso


This then allows me to play the DVD disk without burning.

However video becomes distored on the second video and crashes. I was thinking that mplayer just can't handle it, but I'm not sure if the above is correct.

Hi,

have you tried without the xml (without menus that is) first? That way you can check if the vids are ok. dvdauthor should detect the aspect ratios itself. The following creates 3 titlesets. Each can have its own aspect ratio (one titleset can't have that).
Code:

dvdauthor -o <dvd_dir> -a <mp2+en for instance, check dvdauthor -h> -c <chapters, e.g. 0:15:00,30:00,...> video1.mpg
dvdauthor -o <dvd_dir> -a <mp2+en for instance, check dvdauthor -h> -c <chapters, e.g. 0:15:00,30:00,...> video2.mpg
dvdauthor -o <dvd_dir> -a <mp2+en for instance, check dvdauthor -h> -c <chapters, e.g. 0:15:00,30:00,...> video3.mpg
dvdauthor -T -o <dvd_dir>
mplayer dvd://1 -dvd-device <dvd_dir>
mplayer dvd://2 -dvd-device <dvd_dir>
mplayer dvd://3 -dvd-device <dvd_dir>


If this all works well I suggest getting a frontend for dvd authoring/menu editing if you like. There are some around. I used a gtk2 gui once, which was really ok back then, can't remember its name, though.

Good luck

Hello, thanks for the help, but it just does exactly the same as the above code.

I'll think I'll try to use a GUI now, this is just a bit too messy, thanks anyway. :)
