Yep - about that - there's a new library called libiec61883 (available
from www.linux1394.org in subversion) that supports firewire capture.
I've been testing that capability with massive amounts of assistance
from Dan Dennedy, it's author.  (He also wrote ddr1394.)  I've gotten it
to capture HD streams with a sample program that he wrote, so a release
may be soon forthcoming.

I've got packages available too, if anyone wants to test the capability.

What we need now is for someone to take a look at the sample capture
code included in the package and adapt it for use within Myth.  Anyone?
