[MPlayer-users] WMV Problem: "-ss #" skips 10x the # secs specified

[groups, freeman]

I am trying to use the -ss parm to start playing a WMV file at an 
offset, however it's not working as expected.

Basically it skips ahead about 10 times more seconds than is specified 
with the -ss parm.

For example:
     C:\WINDOWS\software\mPlayer\mplayer.exe        -osdlevel 3 12h29.wmv
plays the file normally from the start. However:
     C:\WINDOWS\software\mPlayer\mplayer.exe -ss 60 -osdlevel 3 12h29.wmv
shows the file starts playing at the 10m6s point.

My setup:
     - XP SP3
     - mPlayer: "MPlayer Sherpya-SVN-r33574-4.2.5 (C) 2000-2011 MPlayer 
Team"

The WMV file is the output from a Logitech webcam, using the 
accompanying "QuickCam" software (version 11.5.0.1169).

BTW thanks for mPlayer - great proggie!
