PowerPoint does not have a native feature to do that - but third party
applications can do that. Not all of them do it too well - and you'll
need a Powerful computer to get better results - luckily many of them
have trial versions and you can check if they work for you.
Some aspects you need to pay attention to:
1. You can not burn PowerPoint to DVD directly with out third party
software, because PowerPoint is not MPEG-2 Video formats which you can
burn to disc directly with common burning software like Easy Media
Creator, Power2Go and so on. you need certain software to convert your
PowerPoint to MPEG-2 or that software has the function of burning
PowerPoint to DVD directly
2. Burn PowerPoint to DVD or disc. Commonly, there are two steps,
first convert PowerPoint to a certain video format such as MPEG-2,
then burn the video to disc. (Here you can use these common burning
software like Roxio Creator)
And there are some software can do this at a time
3. Put the music and the PowerPoint in the same folder, in a word,
everything in the same folder to make sure you burn PowerPoint to DVD
with animations, transitions and audio track retained.
The only way to do this is to get specific PowerPoint to DVD software.
The best I've found is this one:
http://www.ppt-to-video.com/powerpoint-to-dvd-overview.html
this was is $79.95 and is one of the few products that didn't mess up
animations, transitions and music.
The other option is to use Windows Movie Maker but you would have to
start from scratch and insert all the pictures onto it. I believe
Windows XP and Windows Vista came with this free software so you
probably have it. You click on Import Media and select the pictures
you want (press Ctrl to select individual pictures). You can then use
the Auto Movie button to add credits, music and transitions to your
movie. Then burn it to DVD.
Hope this is helpful.
