Hi everybody !

I'm having difficulties with DVD authoring.

I've got a 720x576 source which comes from an analog camrecorder, encoded with the HuffYUV codec. I'm filtering the video with an AviSynth script, and I want to "encode this script" into a DVD format, through FFmpeg (see the command line below). And I want to finally author the file with DVDAuthorGUI.
ffmpeg.exe -i dvd.avs -aspect 4:3 -target pal-dvd -maxrate 9800k -bufsize 2048k dvd.vob

I'm almost getting what I want, except that I've got warning when authoring with DVDAuthorGUI : "WARN: unknown mpeg2 aspect ratio 1".

Indeed, when I call :
ffmpeg.exe -i dvd.vob, I've got : "PAR 1:1" and "DAR 5:4".
Note that "-aspect 4:3"' in the first command line should fix the problem... but it's unfortunately not the case...

After some tests with other software (AVStoDVD), I successed to get these : "PAR 16:15" and "DAR 4:3", with no warning in DVDAuthorGUI when doing the authoring process.

I could stop my experiments with this result (given by AVStoDVD), but as I'm a newbie in DVD Authoring, I would like to know where I'm wrong with FFmpeg. :)

Thanks in advance for any help you can give me :)
