Hello, new here. I'm trying to make a video using multiple Vobs and Toast Ti 6.1.1. In the vdeo mode I can drag three separate Vobs into the menu/edit window. When I begin to make an Image Disc, Toast will demux the first two Vobs and half way into the third Vob I receive error -18774 "couldn't complete the last command because there is a problem with the source material". However, every time I process a single Vob, the image disc is completed.
