nothing locks up, the computer just stops being able to receive the mpeg 
stream over firewire until the bus is reset. this can occur by unplugging the 
firewire cable and plugging it back in, or using gscanbus's reset bus option 
(which sadly is GUI only).

Why it does this, I don't realy know, but it does, and from my understanding 
it happens to quite a few folks, so I figure I'd try and find a solution.
