He's right, 640x480 is the magic number. But more importantly, you need the hardware to output to your VCR. I have a Canopus Pure 3D accellerator card that I picked up for $70, that sped up my preview renderings, and also can output to VHS or SVHS format.(SVHS is the format you would have to record it in if you wanted to send it to a T.V. station.)
