Cannot seek in this file! - big h264

Hello,
I've tried to play a movie encoded with x264 media encoder. In my
movie directory there is 2 files: trailer and the full movie. I am
using mplayer compiled from current sources in mingw environment with
windows XP. Both files are played well but I can jump forward/backward
when I watch the bigger file (more than 6 GB). There is no such
problem with the smaller one.
I want to mention that I add configuration flag for large files so all
my configuration flags are:

./configure   --prefix=c:/mingw/mplayer_root  --enable-mmx
--enable-mmxext --enable-3dnow  --enable-3dnowext  --enable-sse
--enable-sse2 --enable-menu --disable-bitmap-font --enable-largefiles
--enable-static

I tried to rebuild movie index but the result is the same. Every time
I've seen the same message:
Cannot seek in this file.
Cannot seek in this file.
Cannot seek in this file.

My Whole log from the console is:
