Joining part of IFO files for one conversion

[onisama]

I have some anime eps that don't seperate the episodes, intro, outro and previews with chapters (The intro and ep 1 are one chapter, ep2 and 3 are another chapter, the outro is another chapter, and all three previews are yet another chapter -- very screwy). I want to join parts of the ifo files together so I have the intro, episode, outro and corresponding preview in an ifo file for D2S to convert. I've tried encoding each part seperately and just loading them consecutively as I make the image file, but was not satisfied with the playback of the resulting combination. I think I could join seperate project files together with DVD2AVI and then encode and mux by hand, but the subtitles time codes will be a painfigure out. So is there a way to accomplish this or am I screwed. I thought maybe IFOedit might be able to dothis, but I haven't really used it much so I don't know.

Thanks in advance :)
