I have recently changed from having a windows machine to an iMac. I can't find the software to install my camcorder that I already had installed on my windows machine. I plugged in the camcorder to my iMac it picked it up ok. The problem is that it is picking up the pictures that I took on my camcorder but not any video footage. Does anybody have any idea why this is and if so what can I do to get the video footage.
