Re:I have the TRV22 (Score 2, Informative)

I have the TRV-22 and use it all the time on a G5 dual 2ghz. Just plug in the firewire cable (mine came with my camera) into the firewire port on the front of your G5, turn the camera on to VCR and capture away in iMovie or Final Cut. No problems for me other than an occasional timecode break. USB is for accessing still shots from the memory stick.
