*sigh* this is from a pm about the problem, I just forgot to put it here.
I tend to get this when there are track matte's some times, so I have to play with my export settings specifically "maintain data rate/always/recompress" that tick box and drop down. Eventually i can export on uncompressed or huffyuv (Lagarith takes more CPU)
Also those machine specs are not really that good :\ so it may not have enough juice to export.
Alternatively export in chunks... such as export the trouble spot by itself (100 frames or w/e)
*shrugs*
That's all the help I can be usually I have to turn my computer on and off again and futz with those settings before it exorts.
I'd like to add that I cant export more than 10 seconds if I'm using an avs with no filters at all so I have to edit from either vfapi or avi files since vfapi screws up randomly on my pc. There's an approach I recomend to WMM users who keep getting export problems... export in chuncks (workspace bar only) and then replace your original footage , time consuming and a painin the ass but if all else fails and you dont wanna scrap your project... *shrugs*
These are my system specs to put things in perspective:
AMD 4600 Dual core
4 GB corsair (matched sticks of course in their pairs) 800mghz ram
2X 7600 GT TDH Nvidia Leadtech 256mb video cards running SLI
1.3 TB in HDD
Big ass Antec fans
And it still crashes like that even with full system resources allocated to my editing program. But having used WMM for years and putting up with a crash after every single change I really dont have anything to complain about in comparrison <.< >.>
My current solution includes upgrading to premiere pro 2.0 (I use 1.5 and it has a memory leak) and reinstalling a new version of windows (thanks AtomX for trying to halp).
psst I also have trouble with the amvapp3.0 so maybe that is related to your crashes or maybe you should upgrade to it, it seems to help some people :p
