I did a demux of a DVD (ripped as ESs), a remux (with IFOedit) then I launched DVD Shrink. I deselected some subtitles (kept only the first and the last ones) and compressed it to DVDR5. Although I've done this flawlessly in the past, this time DVDShrink simply blanked out all the unwanted subtitle streams: in the end I had a DVD with video, audio and 2 non-consecutive subtitle streams (like [20] and [2A]). I also noticed that DVD Shrink did this in one go, normally it had first to compress the video in one pass, then to recreate the IFOs in the second one. DVD Shrink may use one step only, but this seems to be reserved for the case when no streams are deleted. Any particular reason for this behaviour?

I'd rather say this is reserved for the case where no compression is necessary. What's ESS BTW?

Why are you remuxing with IfoEdit all the Sub streams and then attempting to remove some of them with Shrink. Simply dont mux them in at the IfoEdit stage. Also earlier versions of Ifoedit had major probs remuxing NTSC streams, I assume you have the latest 0.971 ifoedit? Have you also tried Muxman for remuxing/authoring your ES streams?

Well, I know it's strange, but I have a problem, my video processing PC is remote located from my other computers. I had to remux all the streams in their order since I forgot to bring the external original DVD with me at home. The files were already demuxed on my external HDD I'm carrying always with me. And I had to do it over the WE :) What I know is that stream 20 and/or 21 were English and the last one was my native language. So I remuxed everything back all the streams I had and I tested which language is which (in PowerDVD or WinDVD), and I noticed this problem.
