ffmpeg windows build crashes when using 2 pass

[tito13kfm]

when using the compiled version from ffmpeggui02c and using the following command line I get a ffmpeg.exe has caused an error, would you like to report this error to microsoft? (of course not)

ffmpeg -hq -i test.avi -b 6000 -s 720x480 – aspect 16:9 -maxrate 8000 -minrate 2000 -an -vcodec mpeg2video -pass 2 test.mpg

My thinking is I'm telling the program to run in high quality mode, the input file is test.avi, bitrate would be 2000/6000/8000, size 720x480, aspect 16:9, no audio, codec mpeg2video, 2 pass vbr output file name test.mpg

it runs until about 1150 or 1151 frames and then craps out (different spot each time, but very close together) checked for bad frames on the original divx and there are none.

But as soon as I remove the "-pass 2" it makes it all the way through (I assume this enters a sort of CQ mode, or a 1pass vbr mode whatever you want to call it using the default quantize level of 2 (which I can override))

If I try to play the test.mpg in windows media player it's all scrambled. When I open in virtualdubmod it says parsing interleaved MPEG1 file (definately not a good sign). I can watch the video fine there. Everything is close to perfect in fact. But if I try to get file information I get a "An out-of-bounds memory access (access violation) occurred in module 'VirtualDubMod'." Error

EDIT: It's also creating HUGE peaks in bitrate (up to 18000kbps) according to the bitrate viewer in DVD-lab. even though I clearly told it to use a max of 8000

The original file is divx 5.0 according to gspot.

How do i get it to output a proper mpeg2 stream? I'm assuming I need to force a video type with the -f option, but what type, I tried mpeg2 and it says not a recognized video type. I'm kind of stumped. Any help anybody?

checked the ffmpeg forums? i dont think the mpeg2 encoding is perfect yet.
