I have a DVD of a film called 'La Haine'. It has no region coding or CSS and conforms to the DVD 5 standard. This is a very easy disc to back up. However the film is french and in black and white whilst the subtitles are are in white. For large parts of the film the subtitles are completey unreadable. Is there a way to change them to say 'red'?

Thanks in advance.
