Connecting Sony DCR-DVD92 Handycam to iMac

I have a Sony DCR-DVE92 Handycam that uses the small DVD's. Since my iMac can't accept these how can I get my video from the camera/DVD to my iMac? The camera doesn't have a firewire or USB connection. I only have S-Video cable to connect to a TV to play the video on. Is there something I can connect the S-Video cables to that I can then connect to the USB or firewire port on my iMac?

Thanks
