[MEncoder-users] Mencoder x264 encoding problem on Intel

[James Hastings-Trew]

I use mencoder on Windows XP, using pre-built binaries found here ( 
http://ffdshow.faireal.net/mirror/mplayer/ ).
I have the following command line:

mencoder INPUT -aid 128 -chapter 1-1  -sws 9 -of lavf -lavfopts 
format=psp -vf 
pullup,softskip,crop=720:360:0:60,scale=480:-10,harddup,unsharp=l3x3:0.7 
-ovc x264 -x264encopts 
bitrate=552:global_header:partitions=all:trellis=1:vbv_maxrate=768:vbv_bufsize=2000:level_idc=30:threads=2:pass=1:turbo 
-oac faac -faacopts mpeg=4:object=2:br=128:raw -channels 2 -srate 48000 
-ofps 24000/1001 -o OUTPUT

This works perfectly fine on every AMD machine I have tried - dual core, 
single core, no matter, they all work.

This causes mencoder to crash (not just a crash on the commandline - a 
Dr. Watson crash that wants to report back to Microsoft) on every Intel 
machine I have tried - Quad Core Xeon, Core 2 Duo, Pentium 4 with 
Hyperthreading. They all crash in exactly the same way. Mencoder does 
its preliminary stuff, and crashes out on frame 0 every time.

I have tried all of the different celtic druid builds  for various PC 
processors - they all exhibit the same behavior. Encoding using lavc 
codecs works on these Intel machines, but the x264 encoding does not?

I'm not a programmer and I really don't where to start to build my own 
compile of mencoder on these other processors, so my question is: a) can 
someone suggest a build that the above command line will worth with for 
Intel machines running Windows, or b) can you see something wrong with 
that command line that I am just not seeing.

Things I have tried: different audio codec, different container format. 
It works just fine if I change the video encoder details to lavc / 
mpeg4, but thats kind of defeating the purpose. :)
