when I make a project on WMM, I convert my music from MP# to WMA, I convert the WIMP file from WMM to MP4 by saving project to computer. I then convert the MP4 to WMV using a NCH program, then burn the WMV to a dvd. when I play it on a dvd player, the picture is ok, but no sound.

How can I fix this, I have tried many times, with no luck, very frustrated.
