Panasonic usually includes the Mac software program "Imagemixer 3" that imports the videos/photos you have on your camera. If the software isn't included with your camera, try Googling around for the program and it should come right up! I hope this helps. - Omn1cide

Hi,
Here are the required driver files for NV-GS150
http://panasonic.jp/support/global/cs/soft/download/motionDV60E_LE_1.html

Over the internet, you can order it.

You must download and install the drivers and software for the camera into your computer. Go to the Panasonic website to acquire.

Most likely:
weak batteries
on/off switch has internal corrosion
Battery contacts corroded
If fresh batteries do not cure the problem, it needs repair.
Consider the cost of repair vs. replace with another Maxxum 5000/7000 on Ebay. They go pretty cheap these days. They're practically giving away the flashes for those early maxxums, even the 4000 flash.

You need to purchase a IEEE/1394 firewire. They run around $40-$55 for a 5 foot wire. The 1394 end goes into the computer and the other end goes to your AV/out port on the cam.

Simply rewind the tape and record over the old stuff, if you want it completely blank, cover the lense with lense cap and press record button it will just record a black image.
