I used wxAstrocapturelast night. Great program! The only feature I missed was a timed capture, so I had to manually stop each capture after I started it, apart from that I found it to probably be better than K3CCD. It was certainly more stable than K3CCD on my system, which would sometimes lose the video image on my screen while I was capturing. I'll probably stick with wxAstrocapturefrom now!
