If anyone knows of a solution to this, it'd sure come in handy.... I'm dealing with several converters that turn analog audio/video signals into standard DV video. All of them use the FireWire 400 interface, as is traditional for DV devices. My problem is that my Mac, a Mac Pro (4,1), has FireWire 800 ports. I've bought two different FireWire 400-to-800 adapters, both of which make the DV encoder boxes visible to most video capture applications (QuickTime Pro and iMovie, but not to Apple's example code for performing QuickTime video capture on the modern Mac OS). However, in no case can I capture video. No preview of the video shows-up prior to initiating the capture, and clicking on "record" in QuickTime Pro or iMovie produces nothing (literally zero byte movies - no data whatsoever is captured).
I've Googled for answers, and found indications that other people have had the same, or similar, problems, but I haven't found any answers. (At this point, I'd even settle for an explanation of why Apple seems to have screwed me.) If anyone has any insights, please share.
