sometime you download subtitles which are in sub/idx format which is not supported in DVD-Lab pro so you can do the following :

1. Use dvdsupdecode to convert the .sup file into a .txt file and several .bmp files,
with the -bitmap parameter and either the -pal or -ntsc parameter according to the
original DVD you demuxed the .sup file from

2. Open the .txt file in notepad, remove the lines at the start which are similar to the
following ones:

Code:

;Subpictures_20.sup
FrameRate=29.97
Palette=2010
Alpha=FFF0

and instead add a line like this one (depending on the original value indicated by
"Framerate="):

Code:

{29.97}

Also, do a couple global replaces to get rid of the { and } surrounding the subpicture
names, the easiest way is to replace {Sub with Sub and then bmp} with bmp.
Save the file with the ".sub" extension.

3. Load Subtitle Workshop, and open the .sub file you just save as a MicroDVD
subtitle file.

4. Save the file as a Spruce DVD Maestro .son file.

5. Open the saved .son file in Notepad. By default, the lines at the start will read:

Code:

st_format 2
Display_Start non_forced
TV_Type PAL
Tape_Type NON_DROP
Pixel_Area (0 573)
Directory

For NTSC only, change that to:

Code:

st_format 2
Display_Start non_forced
TV_Type NTSC
Tape_Type NON_DROP
Pixel_Area (2 479)
Directory

Also, further down, you'll find a couple of lines that read

Code:

Color (0 1 2 3)
Contrast (0 15 15 15)

Adjust those to match the original .txt file's "Palette=" and "Alpha=" entries, keeping
in mind that they go backwards. So, for our example

Code:

Palette=2010
Alpha=FFF0
becomes:
Code:
Color (0 1 0 2)
Contrast (0 15 15 15)

Save the .son file again with the changes.

6. Now you can import the .son subtitle file into DVD Lab Pro in the same way you
import .srt subtitles. Be sure to set the vertical margin to 0, and leave the "drop frame"
option unchecked (or the "non-drop frame" option checked, depending on whatever
the checkbox actually reads).
