OK, what I’ve tried so far:
DVD Decrypter demuxed .sub: seemingly unreadable by any program.
OCR with SubRip: works, but too troublesome and time consuming with all the character recognition typing.
BMP with SubRip: not sure if I did something wrong, but by the time I imported to DVD-Lab Pro and built the final movie, the subs had lost background transparency, meaning a black screen comes up together with the subs every time.
VobSub Ripper: the output subs are all in capitals.
There MUST be something simple and quick which works ?
One additional question, is there a way to keep a sub track’s original formatting (italics, etc, as per use of <i> tags if it’s a .srt for instance) in DVD-Lab Pro ? The program has built-in support for this stuff but seems to discard all formatting when importing-building a project.
