Editing sound on Korea Drama

Hi,
I have 3 sets of korea drama total 70 vcd disks in which I bought from a retailer shop.
I wanted to sqeezee the 70 vcds into 24DVD disks and I used dix to dvd to convert from vcd to dvd.
The question is the vcd has got two languages ie korean and chinese.
Now all I wanted is to put 3 ep into one dvd disk and all I want is the chinese language taking out the korea language.
Can anyone tell me how to do it by retaining the chinese language only.
Which is the most simple program to use.
Your assistance and explanation here will be greatly appreciated.
