Yes, also OSD displays bad DVD time informormation, exactly like the mplayer GUI.

I knowed lsdvd, but now I've read its help message and I've understood that it's the program that I need, small and stand-alone (not as tcprobe, that comes with trancode): thanks.

The greatest problem is not that I can see the correct total time directly from mplayer, but that I cannot see or encode a  DVD starting from the nth second (using -ss function). Example. I want encode separately, at a constant bitrate, movie credits that don't start at last chapter beginning: OSD/GUI value before "/" isn't in relation with total time value after "/" so I can't use it, but I can't use the corret credits start time displayed by another player, too, because the total displayed by mplayer is uncorrect (and there isn't a linear correlation between the true lenght and the lenght diplayed by mplayer)...

Anyway, thank you

Bye
