[Mplayer-users] Probable race condition issues preclude Mplayer from working on 1Ghz Tbird Athlon (others?)

	Hi.  I upgraded my PC recently with a new CPU/mobo to a 1Ghz Tbird.  But
now mplayer goes into an infinite loop of somekind when it attempts to play
video.  Tested the most recent mplayer CVS just to be sure it wasn't fixed

-=- System info -=-
Kernel version number: Linux shadowgate 2.2.19 #1 Sat Mar 31 19:48:50 CST
2001 i686 unknown
Linux distribution and glibc version: Slackware 7.1 and glibc 2.1.3
gcc and binutils version: gcc version 2.95.2 19991024 (release) and GNU
assembler 2.9.1
X11 version: XFree86 4.0.2
Video card vendor/model: nVidia Riva TNT 1
CPU vendor and type: AMD Thunderbird Athlon at 1,000Mhz
-=- -=-

The infinite loop happens right after the final line in the attached
play.log ('Start playing...').  This affects all media formats, so I think
it's a race condition somewhere in the core.  Very, very annoying, as most
of the software which does video/timing syncing I have has broken at 1Ghz.
The only thing which doesn't break at this speed is Windows Media Player
(tested on another box that my roommate owns, 1.2Ghz Tbird).

Again: mplayer no longer plays all the files it played at 550Mhz, instead
going into an infinite loop.  I suspect a synchronization/race condition. 
Perhaps proper thread interlocking or a more finely grained sleep routine
would solve the issue?
