PAL output not possible??

[pedro.quaresma]

Hello, congratulations for your great app.

My problem is that, although I set the frame rate to 25.0 fps, after loading the srt file, and convert it to sub (with absolutely no problems), when I load the .sub file in VSO's convertxtodvd the following message is displayed:

"The subtitles included in this movie force the video standard to NTSC".

I opened the sub file with subrip, and it always displays a 30 fps file.

Any ideas?

Thx in advance.
