When you first "converted" the two halves, could'nt you have put the 2 files together to get just 1 video_ts folder? If not then you should be able to open both video_ts folders with shrink. After you choose open files, point it to one of the folders, it will anylize it, then choose re-author and drag over the main movie to the left. Go back to full disc, then open the other folder, choose re-author and drag over the other main movie. I must admit I have not tried this with actual video_ts folders, but I did just try it with 2 different ISO's I have on my harddrive, and inside them are video_ts folders, and I was avle to put 2 movies from 2 different ISO's into shrink. Then when you have both movies on the left of shrink, click back up, and save to 1 video_ts folder or to an image. Hope this helps.
