Wow, what software/version is that? I didn't know Meedio supported Chinese chars. Cool!
The software was mainly fetched from this page: http://www.myav.com.tw/forum/showthread.php?s=&threadid=312362 . According to the page, the software is meedio 1.30. I think why Chinese can be displayed correctly is the use of Arial Unicode MS font. As long as meedio does not do things weird, it should display correct language with proper fonts. :)
