Are non-menu stills with audio possible?

Is it possible to have a still with audio as a title item?

I am trying to create an NTSC DVD that contains audio with a still image as the video.  I've created the still from an image of 720x480 resolution via jpeg2yuv, mpeg2enc and mplex.  No errors from dvdauthor when I build the DVD, but when playing it, the still remains onscreen after the audio finishes; it doesn't return to/call the menu. I have to press the menu button on my remote to return to the menu.  I've also tested this with 15-second audio snippets (instead of a full-length song) and the problem still exists.

I intend to have many such titles (among other content) on my DVD and would like to keep the file size of this particular media down.  I know this (stills with audio) works for SVCD...

dvdauthor version: 0.6.14
mjpegtools version: 1.9.0-r1

I've used the following commands to convert an image to a still and mux it with the audio:

jpeg2yuv -j lat.jpg -f 29.97 -I p | mpeg2enc -a2 -f8 -o lat_img.m2v
Output: http://paste.pocoo.org/show/449195/

and then:
mplex -f8 -o DONE/lat.mpg lat_img.m2v lat.ac3
Output: http://paste.pocoo.org/show/449196/

DVDAuthor XML:
<dvdauthor dest="dvd" jumppad="no">

<vmgm>
</vmgm>

<titleset>
<menus>
<pgc>
<button> jump title 1; </button>
<button> jump title 2; </button>
<button> jump title 3; </button>
<vob file="menu_fin.mpg"/>
<post> jump cell 1; </post>
</pgc>
</menus>

<titles>
<video aspect="4:3"/>
<pgc>
<vob file="nebula.mpg"/>
<post>call menu;</post>
</pgc>

<pgc>
<vob file="lat.mpg"/>
<post>call menu;</post>
</pgc>

<pgc>
<vob file="mnc.mpg"/>
<post>call menu; </post>
</pgc>

</titles>
</titleset>
</dvdauthor>

Both 'lat.mpg' and 'mnc.mpg' are the items in question.

dvdauthor command used to build DVD: dvdauthor -x dvd.xml

Note: I am not interested in moving to any additional tools (especially if they are GUI-only) for mere simplicity/just to get this done nor am I interested in settling for turning the still into a video that displays duplicates of the same frame.  I just want to have closure on whether or not I can have a properly-playing title that consists of audio with a still as the video.

Thanks :)
