By default, DVD-Lab Pro returns to the VTS root menu at the end of each slide show (Program Chain). To play back the random slide shows continuously, we have to return to the pre-command section of the slide show 3.1 to choose the next randomized slide show. The following screen shot of the Connections window show the pre-command section of the slide show 3.1 (PGC 3) with a plus sign symbol.

We redraw the links for the slide shows 3.1 through 3.5 so that the playback is returned to the pre-command section of the slide show 3.1 as following. We can generate the DVD image by "Compile DVD..." after this procedure is completed.

DVD-Lab automatically generates the virtual command (LinkPGCN) to loop back a motion menu. You can skip the following section if you are satisfied with the quality of transition of the root menu. On certain DVD players, this command may show a noticeable discontinuity when looping back a video motion menu. If you want the looping back seamless, the virtual command LinkCN should be used instead of LinkPGCN. LinkCN is designed for this purpose since it is more efficient and has a lot less processing overhead requirements than LinkPGCN. Since DVD-Lab Pro does not allow changes to its generated virtual commands, we need to use additional tool, such as IFOEdit to make the required modifications.
