Hi, SassBot...
I found a bug in version 1.0.0.
When I edit idx/sub created BDSup2Sub++ and use "Edit DVD Frame Palette" to set black background in one line...
In my TV not appears black background on line that I have set, but the problem with randomly background come back in many lines of subtitle.
Like this:
Here is the idx/sub with the problem:

The bug of randomly background in many lines back again.
Note: I use the same image, because the problem is the same
