This is such a basic question that I'm embarrassed to ask it, but I am not able to find the answer. I downloaded the software so I could create a high resolution DVD containing several (4) videos stored on my computer as MP4 files. The DVD burner app does not recognize that file type. The valid flies are only .vob .ifo and .bup. Seems like MP4 and similar video file types should be available. How can I do this? Thanks!
