I have a dvd that I burned from a vhs using a vhs/dvd recorder burner. This created a ifo/vob file. Does your Movie Edit Pro 15 or Pro 15 Plus have software to convert this vob file to an avi file. I need to convert this file so I can insert it in a slideshow presentation.
Basically the answer is "yes". You can import DVD (*.VOB) files into the program and you can output AVI files (using whatever codecs are installed on your system and suitable for the export).
Not sure what program you want to import the AVI files into to create a slideshow, but if you consider buying Movie Edit Pro 15, you might as well do your slideshows in there, without any AVI conversion procedures. The program will probably offer you more features and options than most basic slideshow applications.
