PPS (PowerPoint show) is the PowerPoint file that can be opened by starting slide show directly instead of opening the editing view. You can "convert" a PPT file to PPS file simply by renaming the file extensions. To play a PPS file, you need PowerPoint or PowerPoint viewer installed on your computer.

A.Deliver to your families or friends but do not want it to be modified.
B.For merchant or business show
C.For some celebration thing
D.For teaching or training
……
We can modify the PPS files by renaming the extensions breezily so if you want to send your presentations to others and keep your presentations originally, PPS is not the best choose.

Let see PPS for merchant and business show. It is the good idea to use PPS for merchant and business show because it can economize the advertising fee. The most import thing is we can design and revise our advertising easily if we like, the hardware we need is a computer and a projector.

Using PowerPoint for celebration like anniversary celebration, graduation ceremony and birthday party is also a judicious decision. It impressed me much when I was invited to a graduation ceremony with my senior. They created a wonderful presentation and put lots of pictures which are the wonderful memory of their college life.

I don’t know if you have noticed that there are some inconvenient things when we use the PPS for the merchant and business show. Or maybe you have been puzzled in the birthday party without a projector. We just have computer, DVD player and TV. Did you have even thought converting your presentations to DVD and then you can play back your slide show on a DVD player or on TV? If we can, the problem can solve completely!

LCD TV can be found on the street everywhere and the ADS rolled. At home we have TVs and DVD players, why not take the advantage of these sets and play your presentation on them?

OK, now it’s a thing of converting PPS to DVD, or burn PPS to DVD.
PowerPoint does not have the built-in ability to save presentations as video files or other video formats such as DVD-Video and, even if it did, there would be significant losses of interactivity (because DVD-Video and PowerPoint slide show have very different capabilities in this area) and loss of visual fidelity (DVD-Video resolution is less than typical computer display resolution and most television will not render colors the same way that a computer display will). And how can we do this?

Two solutions of converting PPS to DVD:
1. Windows Movie Maker (WMM), Windows XP and Vista contain this free software so you probably have it. But the troublesome thing is, you must save the presentation to a series of images and then import all the pictures onto WMM. Click on Import Media and select the pictures you want to make a movie. Finally you can use a third-party program to burn the movie you made to DVDs.
The advantage of this method is that it won’t spend you a cent, but all animations, transitions and videos will be discarded.
