In the past, I used Srt2sup to make my subtitles. And although it worked quite well, to get the correct IFO colour palette was always difficult, as well as synchronizing the subtitles.
That's why I've developed SubtitleCreator, and since then, it has been improved by the open source community as well. For example, others have developed an optimal anti-aliasing filter, a filter to display the subtitles on top of your DVD, and developed different import filters, such as support for VobSub and Closed Captions. It's even been used for Karaoke DVDs.
Just give it a try...
