Split screen viewing using bullet cams for car

[kylie]

Hello I am wanting to set my video camera to run some bullet cams in the car for track days and have it play back all the images/movies in one screen like you see in proper race cars. I just recently bought a Sony Handycam DCR-TRV22. I take it there is a mode that needs to be set-up somewhere on the camera and special software to buy for the computer? I got no idea, I just want to do it.
Any help would be much appreciated.
Cheers
Kylie

Hey thanks so much for the great advice and plenty of options, cripes gives me plenty to think about. I will sift through those web links and see what I can do for now just using a single video recorder. Perhaps will invest in another when I start getting a bit more serious about this racing. Bound to keep me broke Thanks all!!
