Yeah, I found the media player avis dont work which is why I convert from wmv. I use a firewire card and cable to get the footage onto the computer.
Also, a question cause I think I might be cheating
Someone asked me about this shot at DeviantArt today and they asked "surely you track by hand, at that mag." At the magnification I was using, it was unpractical to let saturn 'drift' across the field of view because it would be gone in like 2 seconds or less. So, I centred saturn on the camera screen and dragged the scope (by hand, just pulling it) whilst imaging and keeping saturn in the centre of the screen. So it is cheating to say 'no tracking' if I was was pushing the scope after saturn?
