SERBIAN Subtitles will be rendered in white with black outline at 28 point size using the Arial typeface with ISO8859-1 characterset centered at the lower part of the screen where they usualy resides. Support for other charactersets like Cyrilic, Greek, Thai, Chinese etc. will be added in future updates like its stated on my web page and on the forum...However you can add any type of subtitles to an AVI before encoding to MPEG2 and then you'll have it on DVD after authoring...Please check here on my forum how to do it:
