Get yourself a wireless camera then plug the recivers video output into the camera's video in port. ALL video cams should have a "video in", but you may have to look in manual how to access it. My camera I have to enter menu's and change the RCA ports from the default output to input, then I record while in VCR mode (like a normal VCR ..

Some wireless cams also do audio, that would be cool if you have a nitro . They dont weigh much, unlike strapping your video camera onto the car (ouch, heavy and possible damage to $$ video camera)

My Camera is a MiniDV type, I can get video on to PC using analog video out ports or firewire (I use firewire). Some of the more expensive cameras use DVD-RAM disks (no tape), if you have a DVD-RAM drive you should be able to read them (not many people will have a DVD-RAM drive, this is not a DVD or DVD-RW/DVD+RW drive)
