I have a movie in rmvb format, this movie has 2 languages which is Mandarin and Cantonese. When i play in my computer using RealPlayer, i just need to adjust the Balance in the volumn control left or right to choose the language to listen to. But now i want to convert the movie to DVD format and burn it to a DVDR, but what should i do to make sure i can select the language to listen to when i play in my DVD player ?
