DIVX6 XSub subtitles and help

Hi,
I am having a problem converting subtitles. I converted the file using divx convertor hi def format. I converted the movie and it came over with all of the subtitles in tact. When I play it through the divx player the subtitles show up fine. If I rip it and play it on my divx dvd Player it plays the subtitles fine. When I play it in Windows Media Player it doesn’t understand the subtitles. I think they are called xsub subtitle files in the divx6 file. When I load the divx avi file into divx2dvd it fails to recognize any of the xsub subtitles? Is there any program that can convert divx6 subtitles straight to a dvd from this xsub format?

Thanks a ton,
John Blackham
