I think the problem lies with my total ignorance of computers and camera linkage. I've tried both links you supplied and watching the motion instructions makes it all sound easy. Probably with my TZ10 that was what I did without a problem. However, after the instruction to plug my camera into my computer, the picture which appears on the clip is not what comes up on my iMac. Mine just comes up with all my recently added photos in which are included the video clips (without motion obviously). I want these taken out of iPhoto and put into iMovie but I can't do it. Any ideas?
In desperation I have been both to a camera shop and then to P C World to try and get this sorted out. Basically I have had to buy a card reader, insert the little memory card. Up should come a 'No Name" heading. I am then supposed to click on that which will then display 3 boxes, one with a Q in it and the word 'Private'. By clicking on the 'Private' box my video clips are supposed to appear - this does not happen. In fact clicking on the 'No Name' heading just opens up the iPhotos - no sign of the video clips. So now what do I do?
