[MPlayer-cygwin] DVD startup mingw vs cygwin

[Gianluigi Tiesi]

I've made some tests, I think the slow startup on mingw
is not related to seek and open file, I've tried
also using native CreateFile and SetFilePointer functions, but
something is different, here both logs on similar configurated builds:

Maybe you are playing a non-interleaved stream/file or the codec failed?
For AVI files, try to force non-interleaved mode with the -ni option.

Actions are a bit differents, please also note:

on mingw:
...
Checking for MPEG-TS...
TRIED UP TO POSITION 72650, FOUND 0, packet_size= 71, SEEMS A TS? 0

...
system stream synced at 0xD (13)!

on cygwin:
...
Checking for MPEG-TS...
TRIED UP TO POSITION 72650, FOUND 47, packet_size= 0, SEEMS A TS? 0
...
system stream synced at 0xD (0)!

in demux_mpg.c: line 345
mp_msg(MSGT_DEMUX,MSGL_V,"system stream synced at 0x%X (%d)!\n",demux->filepos,demux->filepos);

how cygwin can print out:
system stream synced at 0xD (0)!

demux->filepos is changing while mplayer is printing the message?


I'm still investigating... someone has ideas?
