way back in 1980 when i was working on the computer animation for TRON we had frame drop problems every time the electroplating factory sharing the same power grid with us turned their machines on or off.
you might want to isolate your power supply - a dedicated circuit? or you might want to separate your cables - put the firewire a few feet away from the power cables. back in the day we took our ribbon cables to a place that wrapped them in a copper braid for electical shielding. --- In videoblogging@yahoogroups.com, "Adam Quirk" <[EMAIL PROTECTED]> wrote: > > Amazingly, this problem decided to solve itself.
