I'm working through one of the guides on here to rip a dvd-9 down to dvd-5:
SmartRipper to get the main film files off, demuxing to new files as I go, losing subtitles etc to make it fit. I don't need to ReMPEG as the size is just about right for a DVD-r, so I get to the IFOEdit bit.

I open VTS_01_0.IFO, then, as instructed, double-click on VTS_PGCITI. The next thing I should do is click on VTS_PGC_1... Except this has a playlength of 8 seconds and VTC_PGC_2 is the main film chain. That's not to mention the other 10 chains after it...!

Is there a way of killing off the other (unwanted) chains to just leave the film itself, or are they integral?
