In V8 I have created regions and named them with subtitles.
I then used the Export Regions as Subtitles script to create a .sub file.
BUT
In DVDA, when I create a Subtitle Track and go to import these subtitles, I get this error:

"Warning: An error occurred while opening one or more files.
An invalid argument was specified."

Any ideas what may have caused this?

EDIT - Now solved - I found an unwanted Region which was probably overlapping and corrupting the .sub file - all now working...
