windows movie maker. I've converted from MP4 to JPEG and created a trial movie. I've clicked on 'burn to disc' and selected the movie to be burnt to the disc. When I clicked on burn to disc again nothing happened as I right clicked on the movie and clicked on 'send to E drive etc.' It makes all the noise one would expect but nothing goes to the disc. I've tried DVD+R and DVD-R discs. I can't work out where I'm going wrong.   As I'm probably average pc literate it's taken me a while just to get to this stage.
