Hi, before burning, PhotoVidShow will check the size of the VIDEO_TS folder which it created when encoding/burning your project. This is located in the folder the project was encoded in. The default (as from the ‘Author video wizard’ screen) is Documents\PhotoVidShow\Aurthored\”Project name”\VIDEO_TS
This VIDEO_TS folder is basically the created DVD image stored on your hard-drive, and this is what is burnt to the DVD
This VIDEO_TS folder is created each time you encode your project (done during the burning project). This is not deleted so you may want to check this now, to see why PhotoVidShow thinks this folder is over 4.7 gig
If it is over 4.7 gig, then this means your Slideshow is too big to fit on a DVD. Options here is to either re-encode a smaller project or there are free applications like ‘DVDShrink’ that will reduce it (by quality) such that it will fit on one DVD. From DVDShrink, select open files, then select the VIDEO_TS folder
Also worth remembering that the input material may be smaller than the final DVD VIDEO_TS folder, especially for a video files like mpeg4, as the final DVD must use mpeg2 encoding which is older and can not compress files as much as newer ones ( e.g. divx mpeg 4 etc).
