Hi, Cruch!
I have the same problem when trying to save .AVI with high resolution.
Try following - it is working for me on winXP pro + pro QM card:
Choose a very simple and short graphical animation - about 5 or 10 seconds long, for one Zone only.
Test normal playback, that preview image looks well.
Select Normal quality (not enhanced), if your processor is slower than about 1.5GHz.
Select .AVI output with resoluton 100x100 pixels, without audio.
Save video as Uncompressed.
This should work well. If this works for you, try to improve the parameters and seek for an error.
I'm, adding audio afterwards, when compressing video to .WMV format. It is not so time consuming - for me it takes additional double of video duration, beacuse of Two-pass encoding.
When creating video with high resolution (PAL production size = 720x576), I got the same error as you. Error appears when saving to Uncompressed file. Haven't tried other compressors.
By the way - how much RAM do you have in your PC? this might be a problem...
Aly.
