mythpreviewgen is run on the host that recorded a particular recording.
That said, why do you need a separate backend for an HD-PVR? Why not
just hook it into your master backend, which seems to have sufficient
resources for creating previews and running jobs on the HD-PVR
recordings (so, presumably also for dumping data from the HD-PVR to disk)?
