My understanding is that the Victors take more current to control than typical PWM controllers can source, which would explain exactly what you are seeing. I remember IFI selling "converters" that probably just amplify the current that the speed controller can draw from the PWM line. You can easily create a buffer with an op-amp and a 5 volt supply voltage. I also bet there are other chips that some of the other guys can point you to that also will "amplify" the signal.
