Thanks for your help, Olivier.
I think we're more looking for a user friendly software that can rip/encode
in batch in the least amount of time - does not have to be free -...and also
essential is that the files would be universally playable on Quicktime or
Windows Media Player.
Best regards,
Julie

If your goal is to burn DVD subtitles into MPEG-4 video, I used mencoder,
avisynth and ffmpeg a while ago to do such thing. I guess this would be
pretty easily scriptable since it's all comand-line based ...
1°/ Extract DVDsubs from VOB file :
mencoder input.VOB -ifo input.IFO -vobsubout subtitles -sid 1 -ovc frameno
-nosound -o nul
2°/ Make Avisynth script :
LoadPlugin("D:Program FilesAviSynth 2.5pluginsVSFilter.dll")
DirectShowSource("VTS_01_1.VOB", fps)
VobSub("subtitles.sub")
3°/ Encode to MP4 :
ffmpeg -i input.avs -vcodec h264 -s 384x216 -b 500k -g 125 -bf 3 -b_strategy
1 -flags +loop -coder 1 -acodec aac -ab 128k output.mp4
I uploaded a little sample with french audio and english subtitles ( play it
with VLC, since QT Player doesn't seem to play audio. Probably a 5.1
downmixing issue ... ) :
