OK, I'm prepared to be scared again:
here is another TS sample with sub which can be extracted and the subtitle can be viewed in VLC.
After I extracted the DVB Subtitle with ProjectX and loaded the IDX file, for SUP conversion I have strange grey colors and I don't know how to modify these coloros to look the same way if I want IDX+SUB. For this subtitle is nice to see how the filters are acting.
I don't know how are working the colors for SUP subtitles but can be made some option to have some colors like: white subtitle, dark grey antialias and black outline? I think the most used subttiles are white with black borders, and sometimes yellow instead of white. Of course, the white to be a little grey.
enjoy,
