I have this 500 meg avi file and i want to make a VCD out of it. If i select VCD its says i need 800megs of disk space, so with that i insert a DVD and select DVD-video but now its says i need 4.8 GB's of space...how come? This is confusing and annoying because i want to have this movie on disk. However, if i burn this 500 meg on a data disk it fits on fine on either CD or DVD. I'm using Toast btw.
