I have been experimenting with this. By creating a new entry in Devices.ini with the following information:
This creates an mpg movie that plays fine in Media Player Classic(with Subtitles!) but wont play in Windows Media Player (no image, no sound but no errors reported). Not sure why this is.
My source is a ripped DVD with ac3 audio. I know that libavcodec (which is used by Mencoder which, in turn, is used by CloneDVDMobile) supports copying of the ac3 soundrack rather than re-encoding it but I havent figured out whether it is possible to access this option by editing the Devices.ini
Anyway, hopefully this information may help someone to investigate further. It seems that getting CloneDVDMobile to produce full quality MP2 files with subtitles and ac3 audio is ‘almost’ possible.
If we (or Slysoft!) can get this working then we can have subtitled movies that will stream to Media Center Extenders (i.e. Xbox 360) which is, surely, going to make CloneDVDmobile a must have solution for a whole new set of customers!
