[FFmpeg-user] Problem creating DVD menu mpeg

[Mike Martin]

As people probably know a DVD menu needs to be a DVD compliant mpeg
video with an audio stream

previous to upgrading to F16 and ffmpeg-0.8.5 this worked

ffmpeg -v 2  -i /storage/burn/dvd_tmp/2-%d.png  -f s16le  -i /dev/zero
  -s 720x568 -t 15 -shortest -qscale 4 -acodec mp2 -ab 64k -ar 48000
-ac 2 -aspect 4:3 -y test.avi

(a group of png files combned with silent audio)

however now this is what I get

any ideas (the avi is a halfway house)
