The message from ffprobe about an "unsupported codec";
also:  http://ffmpeg.org/pipermail/ffmpeg-user/2014-January/019248.html

However, my immediate problem seems to be solved.  Thank you for your  
help on this.

Thanks for the hint.

Recreated the input file menu.mpg from an old static image "menu_outline.png":

ffmpeg -loop 1 -i menu_outline.png -vcodec png -t 4 bg.mkv
ffmpeg -f s16le -ar 48000 -ac 2-i /dev/zero -ab 224k -t 4 -acodec ac3  
-y tmp.ac3
ffmpeg -y -i bg.mkv -i tmp.ac3 -target ntsc-dvd -aspect 16:9 menu.mpg

Output from ffprobe is now:

Stream #0:0[0x1bf]: Data: dvd_nav_packet
Stream #0:1[0x1e0]: Video: mpeg2video (Main), yuv420p(tv), 720x480  
[SAR 32:27 DAR 16:9], max. 9000 kb/s, 29.97 fps, 29.97 tbr, 90k tbn,  
59.94 tbc
Stream #0:2[0x80]: Audio: ac3, 48000 Hz, stereo, fltp, 448 kb/s
Unsupported codec with id 1145979222 for input stream 0

The command
    spumux "menu_buttons.xml" < "menu.mpg" > "menu2.mpg"
now seems to work without errors.

Questions:

Spumux needs an input video with a dvd_nav_packet stream to create a menu?

The ffmpeg option "-target [ntsc|pal]-dvd" creates an dvd_nav_packet  
stream, even though it is "unsupported"?
