I have a Sony DCR-TRV17 .
I don't know the brand of the firewire cable , but it's an aftermarket and quite chunky, the connectors and cable are finished in a soft clear plastic and it's about 6 feet long . I seem to remember the cable that Apple supplied with the first DV iMac was more slender and flexible .
I'm using iMovie 2.1.2 on OS 9.2.2
It pretty much happens with everything that I do , which is mostly TV stuff recorded to the line in on the camera and then from the dv tape to the eMac . A program will capture to the iBook fine but then beep when the same program on the same tape is captured to eMac . It's only occasional like once every 15 minutes or so .
I wish I had another recorder .
