burned DVD does not allow to select audio or subt language

[juabba]

my dvd is working ok playing disks recorded before with xtodvd 5.

I convert and record to a dvd a xtodvd 7 project with 2 films.
both films have two audio and two subtitles each

when I try to play the new xtodvd7 DVD project ( two audio and two subtitles each) the screen opens all right ,, showing two lines,, for each film.
when I click over any title, instead of going to the screen showing audio and subtitles selection, it goes directly to the start of the selected film, and plays then all-right.
But I don't have the chance to select audio and subtitles language.

have carefully looked to the configuration options of xtodvd project and did not find any parameter connected to this estrange behavior.

thanks
juan
