When you say upgraded to the latest Ubuntu, what exactly did you upgrade?

Did you recompile MythTV and the required FireWire packages?

And what firewire chipset are you using? I'm trying to track down the problems 
people have with firewire and one thing that seems to keep popping its head 
up is the VIA firewire chipsets. You said you had it working except for 
complete failure requiring reboot after a few weeks, which is a new case for 
my findings.
