I actually tried that - it didn't seem to work. I only tried one of the deinterlace types though (the one that said like "blend both fields - recommended") so I might have a better play around with it.

Do you know what the exposure time is? 1/30s? What's the frame rate?

I can lower the exposure, though I think it might just be a digital effect. The camera defaults at 1/50 and goes into the thousands (ie. 1/2000). The second satellite I captured had the lowest exposure setting (at about 1/125 I think), so I suppose that might be the reason why it did seem to have better frames?
I'm not really sure of the frame rate of the camera... I just always assumed it was 30 fps. Regardless, it seems VirtualDub only wants to capture video at about 8-10fps - which could be the problem with a lot of the 'two ghosted images on one frame' issues (ie. the computer is trying to shove more frames into the slot for only one frame). I'm not sure if this is just a computer limitation (as in, whether my computer doesn't have enough CPU or whatever to transfer the file at full capacity).
I think my biggest fix to the long blurring images will be to just get out more often and practise hand tracking the satellites. The more smooth my motion the more stationary (relative to the camera movement) frames I'll be able to capture.
