Transcoding + subtitles sometimes break aspect (sony)

Hi,

I have an ex720 sony. Serviio works most of the time, but sometimes transcode doesnt start, and sometimes it breaks totally aspect ratio. Video goes from 16:9 to someting weird like 24/9 on the tv, ^^.

Trying to figure out why, here is the transccde called:

"C:\Program Files\Serviio\bin\\..\lib/ffmpeg.exe" -threads auto -i S:\a.mp4 -y -threads auto -c:v mpeg2video -pix_fmt yuv420p -b:v 17000k -maxrate:v 17000k -bufsize:v 17000k -vf pad=720:405:0:2:black,setdar=4:3,subtitles=filename="S\\:/a.srt":original_size=720x400:charenc=UTF-8 -r 24000/1001 -g 15 -c:a ac3 -b:a 384k -ac 2 -map 0:0 -map 0:1 -sn -f mpegts C:\tmp\Serviio\transcoding-temp-23787-sony2011-ORIGINAL-f8eed7b8df23e7e4f2c6d7a01d8258d9.stf

original file is 720x400. The temp file is 720*404, (but looks 1:1 when i open it) .

What can be the source of this issue ?
ffmpeg -i on source gives:

any hint ?

[zip]

what if you remove ",setdar=4:3" from the transcode command and run it manually?

what if you remove ",setdar=4:3" from the transcode command and run it manually?
