Trying out firewire recording from my DCX-3200, I've had a few, like the one I provided as a sample. I can pretty much guarantee a crash from some channels, after 0-byte recordings. At least if I can get mythbackend to restart so later recordings aren't missed, I can ride out the weekend and then put my HDPVR in place. I have a message queued to report on my experiences with it.

Up until this round of experimenting I've only ever had the FE blow out, and that was in my over-pushed 0.21 setup. But if I can get auto-restart built in  I figure that's a good thing in any event.
