Tiger/firewire Problem, Not Hard Drive Related...

[onebigfatoaf]

Ever since I installed Tiger on my 2 G5s at work, they haven't been reading firewire output from Final Cut 5, or After Effects 6.5.. Its as if they don't exist, yet a firewire external drive that i have hooked up does boot. Any ideas on how to resolve this?

Also I'm having a similar problem with a blackmagic video card i just installed. If anyone knows anything about that, that would be great.

Thanks a lot.
