Dvdlab doens't create ifo files

[bezhan_o]

recently dvdlab pro has started acting wierd. I've been using it for a while now but haven't run into this kind of a problem ever. I have a dvd that i am trying to burn. There are 11 video clips which altogether about 90 minutes. Encoded through main concept and elementary ac3 audio tracks. I have two menus. The first has a link to the "play moive" and one to a scene selection menu. The scene selection menu links to eight chapter points. Anyway, the problem is that dvdlab only creates vob files and no ifo or bup files. the vob files are also named oddly. The file names are VTS_01_1.vob to VTS_01_9.vob. i know this is not the right file names but this is what dvdlab pro generates. Any body know what's wrong here?

after doing a test compile, dvdlab created the ifo and bup files. Keeping the same set up as above, i just deleted the Scene selection menu and tried to compile the dvd from there. To my surprise this time, dvdlab compiled the files correctly. What is happening?

seems to happen to lots of users, https://www.videohelp.com/forum/viewtopic.php?t=245382&highlight=dvdlab+ifo

Something in your scene selection menu is different than the rest of your project. The mpeg motion menu probably. Render as avi, encode in tmpgenc, or Mainconcept, then import.

i didn't create a motion menu. Still still images from the chapter points with some background music in ac3. (the rest of the dvd was in ac3 as wel). I removed the scene selection menu and the ifo and bup was created. Unfortunately, my player did not play the ac3 tracks (see my other thread in dvd authoring) so now i changed them all to wav and hopefully it will work out. its in the muxing phase now.
