I don't think Split will give you the results you want. The best method is to split by chapters, usually the episode 1 will be chapter 1 through chapter 5 (or whatever) and so on. You can set up the first episode, then click in the title bar, (above) and select Copy Source. This will give you another task listing with the title with all the episodes. Then select the chapter range that comprises episode 2, as an example 6 through10, etc. Keep reloading the Source, once for each episode until they are all listed as single tasks. If you have 8 episodes, this will produce 8 different folders, each containing one episode. You can then use Merge Mode or DVD Creator to put them all in one volume. There is a post I made somewhere that illustrates this, if I can find it I will link it here.
