SDM and autofocus

I have a quick question regarding video mode on dslr and the "*" lenses. Can you autofocus while shooting video using a lens with SDM? I have a pentax k-x and I recently purchased a DA*55. Can I use the SDM to autofocus during while in video mode? Currently with the DA 40 I have to prefocus in live view and then shoot video and while in video I have to manually focus.

Thanks

SDM got nothing to do with being able to AF during video, it's all about the camera body.
