I have split many dvds to 2 dvdrs without any problems. The problem I have with Insomnia is after I use IFOedit to split I have to manually add the VTS_01 set. After I do that I get vts vectors and all plays fine in windvd. But when I try to burn with either Nero or Gear Master they give me errors saying that they don't meet the proper guidelines. I have had this same problem with another dvd when the VTS_O1_0.VOB file is 0 bytes. Any thought or help in splitting this. I don't want to have to resort to DVDXCOPY!!!!!!
