My goal is to create a slideshow that has ~800 photos in
it with around 14 music clips. The file says that it is
about 400 MB big and the CD should hold about 700.

I have broken it down into 3 smaller files to see if I
can get it to create, it doesn't really freeze the
computer, but say the initial create time is 60 minutes,
it gets about 30-50% complete and then the time just
keeps increasing and no more completion.

I have been successful with a small 30 photo slideshow
with music....but nothing larger.

Also, with the small video I did create, the slideshow
did not fill the screen when played....It had like a tv
looking screen with sound, play, etc. buttons....Will it
fill the screen so that each picture covers the screen.
