Motion Detection & G7

Has anyone found an MD script that works on the G7, or knows what changes need to be made to existing ones? I've tried a couple and they either repeatedly take shots no matter what delays I try or they don't take shots at all.

I've found for example from Motion detection settings - CHDK Wiki

"rem for get_prop use 205 for DigicII and 206 for DigicIII" if I use 206 the camera just sits there with the focus beam blaring. Only once I've set it to 205 does it actually take shots ... albeit over n over with no motion. Of course the G7 is supposed to be a DigicIII

I've tried disabling the AF beam and even IS as it creates motion between shots.

See right here: http://chdk.setepontos.com/index.php/topic,471.msg16739.html#msg16739 and here: http://chdk.setepontos.com/index.php/topic,471.msg11856.html#msg11856.

And if you still get a shooting loop, increase threshold and trigger delay, and/or increase light, and of course place the camera on a tripod if it isn't on one already.

Please note that the version you posted above is ancient. It's Digic version independent, but it is prone to get into a loop if trigger delay is too low (a few seconds may be too low for some situations) and it has few features compared to the version I linked above.
