Error of GUIforDVDAuthor

[jinjin_jp]

Please help me about the problem of GUIforDVDAuthor.

I'd like to use GUIforDVDAuthor to create the menu for adding to made pural titles,
because it can create buttons which inputted text.
(Now I've been using only DVDStyler, because I think DVDAutorGUI cannot
create text buttons.)

The problem is,
First start-up GUIforDVDAuthor.
Next when I drag & drop the m2v file (NTSC) from upper-left to upper-right,the process is interrupted by error (erro 6: overflow).
I've been confirmed not to change untill newest v.0.92 from older v.0.75.

When the file is PAL, there is no problem.
(The files are downloaded from DvdReMake site 'Prepared VOB inserts'(NTSC and PAL, and another(NTSC) is demuxed from part of some DVD-Video I have.)
Either NTSC and PAL of setting. the result was same.

Does this reason thought a bug, or wrong using method?

I'm looking forward to the the next release.

I heard the method which can avoid this error, and tried.
The method is to change to English from Japanese on setting "programming language" of "region and langeage" of control panel. (" " is Japanese, so English may be incorrect.)
The result was successfull, even NTSC had no problem.
I've experienced or heard the softs like this, for example DVDRebuilde, IfoUpdate, and MakeIt Easy.

But I wonder why NTSC has problem and PAL has no problem when setting Japanese.
