In the end, this is exactely what I want to achieve. But as long as seeking in a DVD title isn't reliable at all, I used to find in which chapter YOURTIME belonged and the starting time of this chapter (CHAPTERTIME). I then only had to seek to CHAPTERTIME - YOURTIME from the begining of the chapter.
Unfortunately, this does not work reliably with a DVD !
depends on the dvd. How far is the final position offset from the one you specified?
It really depends. It can be any time from the begining to the end of the title. Olivier

who said it? seeking in dvd _is_ quite reliable because mplayer will use the time map stored in the ifo files
I used to find in which chapter YOURTIME belonged and the starting time of this chapter (CHAPTERTIME). I then only had to seek to CHAPTERTIME - YOURTIME from the begining of the chapter.
same as above: -ss works equally well when playing dvd:// streams (but not the vob files)

If I take one arbitrary DVD of mine, I get the following chapter list: CHAPTERS: CHAPTERS: 00:00:00,00:03:42,00:06:30,00:12:25,00:13:57,00:17:49,00:24:38,00:29:02, 00:33:08,00:38:27,00:42:07,00:46:42,00:50:24,00:54:15,00:58:33,01:03:33, 01:07:25,01:11:00,01:15:25,01:19:42,01:22:29,01:27:03,01:31:54,01:37:40, 01:44:20, Interestingly though, playing the DVD, the OSD menu (or the V:xxxx console output) starts at 0 seconds, goes all the way up to 3024 seconds and then resets to 0 seconds (I reckon it's where the layer break is). 3024 seconds are 00:50:24, which, surprise, surprise, is a chapter break (chapter 13). This means specifiying an offset below chapter 13 works well, but e.g. specifying -ss 01:03:29 (chapter 16) won't work, since chapter 16 displays 789 seconds as video offset (50:24+ 13:09(=789 sec) = 1:03:33 voilà) btw: before chapter 17 there's another reset, as jumping to 17 is at 24 seconds, oh, what the heck, I'll give you the complete list: chpt time V: 1 00:00:00 0.0 2 00:03:42 223.0 3 00:06:30 390.7 4 00:12:25 745.8 5 00:13:57 837.9 6 00:17:49 1069.6 7 00:24:38 1478.8 8 00:29:02 1742.9 9 00:33:08 1988.9 10 00:38:27 2307.7 11 00:42:07 2527.8 12 00:46:42 2802.6 13 00:50:24 0.0 14 00:54:15 231.4 15 00:58:33 489.5 16 01:03:33 789.0 17 01:07:25 24.5 18 01:11:00 239.0 19 01:15:25 504.0 20 01:19:42 761.0 21 01:22:29 928.6 22 01:27:03 1201.7 23 01:31:54 1493.2 24 01:37:40 1839.2 The Movie in Question is the German DVD of "The Hitchhiker's Guide to the Galaxy", by Buena Vista (Touchstone). -- cheers, Alex

This happens for me with almost every DVD9. Not so much with DVD5. The problem also appears with EDL files. Olivier
