I have been looking for a good app for putting videos on to DVD and to be honest I haven't a clue as I've just moved to Mac from PC. I've read that iDVD is many peoples choice and I've managed to get hold of an iLife 09 disc which has iDVD on it. It also has iPhoto, iMovie and Garageband on it and this may be a stupid question but if I install iLife will it overwrite the newer versions of iPhoto etc. which are already on my mac? Will it delete all my photos too?
