hi guys, i did a slideshow with music with IMOVIE, than use IDVD to burn dvd.

i check the file size after saving in IMOVIE, it was close to 4GB. but when go to IDVD, it dropped to 1.2GB.

i edited the slideshow in IMOVIE & the file size is over 5GB, but again when exported to IDVD, it dropped to 1.2GB.

pls use layman terms as i am not very good in computer stuff. thanks.
