[abubar]

I want to convert divx movie to DVD & burn it .
I used a guide that learn me how to multiplex divx to *.m2v + *.ac3 files & add subs .
I did it .
now the problem that i have 2 part of the movie ( I robot 1.m2v , I robot 2.m2v , I robot 1 .ac3 , I Robot 2.ac3 ) & I want to make DVD from both of them .
I tried TMPGenc DVD Author but probebly i can do it only from one part of the movie becuase even i add the files with new track option , the software was close & nothing happened .
I dont know how to make 1 DVD movie from both parts of the original divx .
can someone help ?
