I have a set of VOB, IFO, BUP files in the VIDEO_TS FOLDER as follows; Incidentally it must have originally been a double-layer because the overall size is over 6GB. VIDEO_TS.BUP VIDEO_TS.IFO VIDEO_TS.VOB VTS_01_0.BUP VTS_01_0.IFO VTS_01_0.VOB VTS_01_1.VOB VTS_01_2.VOB VTS_01_3.VOB VTS_01_4.VOB VTS_02_0.BUP VTS_02_0.IFO VTS_02_1.VOB VTS_02_2.VOB VTS_02_3.VOB VTS_02_4.VOB Using my software player (Cyberlink PowerDVD), if i load Video_Ts.Ifo, the menu shows up (and pauses until i make my selections), and i can play normally, etc. Now i want to burn this into a DVD for viewing on an ext player, and i am smart enough to burn this onto an ISO image (using ImgBurn), Mount the ISO Image (using PowerISO) and test first by using PowerDVD to play it as if i had a physical DVD inserted into the drive. This is where the problems start. i fire-up PowerDVD, navigate to O:\ drive (where the ISO is mounted), but the Menu zips thru (without pausing), and the movie starts on the second part (The second part is actually VTS_01_0.VOB which is weird in itself - i would have expected the second part to be VTS_02_1.VOB, but no, this is the first part). At the risk of answering my own question, it appears ImgBurn did not burn the VIDEO_TS folder as Video DVD, making it instead a Data DVD? How do i ensure ImgBurn burns my vobs as a Video DVD ? PS. I have also used DVDShrink to burn onto one ISO Image with compression, and get the same bad results (i.e. zips thru the menu without stopping and starts on the wrong movie part).
