Hi Martyn, probably too late if you've returned the VM, but you were feeding too much audio level from the VM into your HV30. That's why you heard the motor hum and I'd guess you were on auto in a quiet room.
In the battery compartment of new Rode Videomics there are 3 sets of dipswitches so you can set the output level to, 0, -10 and -20db. The VM is shipped with them set to 0db output which is too loud for the HV30.
Set them to the -10db setting, then adjust the HV30s level on manual, for speech from about 3 feet out ahead of the VM on the cam. Then you won't hear the motor hum.
You'd only set it to -20db when there's giant audio happening like Formula One car races etc. This comes up a lot, RODE are looking at shipping the VM set to -10db.
Cheers.
