i'm having problems converting and burning 6 wmv files, when thay get converted and and burned thay merge into 4.

Can you provide a little more info on what your source files are / what your tool is / and what your expected output should be?

Do you have 6 input files / add them to a story line / convert them to mpg and rip to dvd? Like is it displaying 4 scenes for the 1 outputed video?

More info please...
