Jitter 1.5 has been running flawlessly and speedily on my Windows XP machine.
But, have experienced instability when using Firewire: irregular frame rate, freezing, Max crashing, machine crashing, etc.
Oddly, the situation is identical if it's a camera connected to the Firewire port, or an external drive.
In either case, removing the attached device clears up the problems instantly.
Has anyone experimented with drivers, system settings, etc.
This is not a proper bug report -- just hoping someone has experienced the same, and can offer some tips or solutions.
