Hi,

The problem is that there can only be 1 session to the camera,
so the whatever is doing the preview captures and the full captures need
to be the same program.

This is a bit tricky with just the commandline tool, so you need to write
either your own program (eg. with python bindings), 

From the same program capturing liveview and photos intermixed should work,
if not that would be a bug.

Ciao, Marcus
