Well, I believe Nero will try to reencode the audio and video since its not strictly spec. Just turn off compliance and give it a go. If you have one, use a dvd-rw first! I dont think it will tho, as the DVD and VCD file structures are different. You'd probably need to create a simple DVD first, then burn. Check out TMPGENC's DVD Author. I believe its unlocked for x number of days before you need to register. I haven't used it in awhile, graduated to DVD Studio Pro.
