I've discovered that iChat A/V recognizes my DSR-11 DV/DV-CAM VTR as video input source. Many of my video production clients are Mac based. Thus while I'm cutting video for them I can stream clips over iChat. This saves an enormous amount of time, energy and driving in proofing differnt cuts. It's a really huge help. Right now the only glitch is that it flops the image, but I can live with it.
Anyway, just a tip...
