time line bug, rev 25088 and rc2

sorry for my pool english at first

i'm using MPlayer to play a DVD disc with an external subtitle file, using
command line like:

mplayer dvd://1 -sub 1.srt

the movie played smoothly without any problem, but the time reset at about
1:26:03, the movie goes on continuously, but the time goes on from 0:00:00,
that makes the subtitle goes from the beginning...

that really confuses me, why did this happen?

i'm using vista, and Gianluigi Tiesi's rev 25088 patched build from here:
http://oss.netfarm.it/mplayer-win32.php

i just tried the non-patched rc2 build, the bug is there too, but act
different, the time do not went back, but the subtitle still went back :(
