Whenever you insert a movie (or a movie as an object) within PowerPoint, it is invariably linked to the presentation. In fact PowerPoint cannot embed any movies within the presentation - that's probably sound reasoning in the first place because embedded movies would balloon up PowerPoint file sizes like nothing else!
Now for the bad part - PowerPoint is not too good at remembering link locations. As far as the presentation and the video files are on the same system, you will not face any problems. However, if you decide to move or copy the presentation to another system you'll discover that PowerPoint cannot locate the video files - it won't even offer to find the links for you. The solution is quite simple - assemble all your video files in the same folder as your presentation even before you insert them into PowerPoint. And yes, only insert the videos into a presentation that has been saved at least once.
