If you search through Yahoo, you may find so many software suggestions about
PowerPoint to DVD and PPT to DVD, I don't know which one is the best
solution, but I know basic features of the software should have
1. Fast to load
The program should load as quickly as possible so that the user receives a
quick response after inserting the DVD into the drive or DVD player.
2. Full inform
The user should be provided with information about who created the DVD and
what it contains.
3. Easy navigation
Leave it up to DVD viewers to decide which presentation they want to watch
and in what order. You can also give your users the option to watch a
presentation again or to skip it.
4. Conversion Speed
I know it's a long time when you are converting a large size PowerPoint. We
do hope the software do things quickly and we can even minimize program to do
other tasks during the process.
5. Video Quality
The Video quality I mentioned here refers to three things: Definition, Size,
and Compatibility.
Definition and Size means that when you are watching your PowerPoint on TV,
it should be clear enough and the video size should fit to the screen.
Compatibility enables you to play the DVD on different DVD player. It is
better for you to play your DVD presentation on most popular DVD Players.
Hope it can help you!
