Digital Origins' FireWire card and FireWire extension conflicts

William Kucharski writes: "Digital Origin's EditDV video editing software can be purchased with a FireWire card to give FireWire support to older Macs that came without native FireWire. Unfortunately, the latest version of EditDV, 2.0, installs Apple FireWire 2.1 extensions for older Macs when you do an install. (The EditDV CD contains FireWire 2.1 and FireWire 2.3 for newer Macs.) The problem is there is an incompatibility between FireWire 2.1 and Mac OS 9.0.4 that will cause a startup crash (illegal instruction error). See also this related MacFixIt item on this conflict. Digital Origin's Web site correctly states that you must use FireWire 2.2.2 to support their card. However, FireWire 2.2.2 will not install by default on an older Mac; you must use a utility such as TomeViewer to extract the FireWire extensions and install them manually." Making matters worse, William claims that "attempting to use anything newer than FireWire 2.2.2 with the Digital Origin FireWire card will cause the Mac to lock up upon attaching a FireWire device." As Apple no longer includes 2.2.2 on their Software Downloads site, this turns into a Catch 22 of sorts.
