Type Vietnamese in Video

[aluu]

Hi everyone,

Does anyone know how to type other languages such as Vietnamese or Chinese for the title of the video clip in Ulead Video Studio 9? I have tried to type in Vietnamese, but it doesn't work. I even tried changing to some Vietnamese fonts, but still doesn't work. Note that I use VPSKeys 4.3 to help me typing in Vietnamse. So what can I do in order to be able typing in Vietnamese in this program?

Thank you very much for any helps.
