Manual VCD Show w/ Music - auto advances
VCDs work differently to PC slideshows especially with music.
With VCDs, your music and pictures are turned into a movie ie the sound and
pictures are combined together. With a PC slideshow they remain separate.
This means that with a VCD you can't skip from picture to picture without
skipping the music too. The next button takes you to the end of the music (back
to the start if you have one music track)
