It has been amply discussed elsewhere that timecode syncing via firewire simply does not work properly on the HVX200 -- the different cameras will have timecode within a second or two of each other, but that is as close as it gets.
That said, there is an alternate approach that actually works -- use a single remote to simultaneously set the timecode preset on as many HVXs as you want.
