Can anyone please help me with the following subtitle problem:

Normally when I need to add subtitles to my movie, I use SubSync to synchronise them, save them as a .srt and then convert them to sup using Srt2Sub and add them using VobSub.

I convert the .avi to mpeg and use IfoEdit to author and Nero to burn. I haven't so far had a problem in doing this.

However, I followed the same procedure above today and when I played back my movie after encoding it, I saw that it seemed to have the same subs twice on top of one another. However, now when I play back the avi, it suddenly has one set of subs!!

Thanks
