I'm guessing that the IDV display in in the native radar projection.
Google Earth only supports rectilinear projections.  Use the 
Projections->Use Displayed Area menu to set to a lat/lon projection.
You can then zoom in before saving.

Even with the overhead projection, I notice we're still a little off.  That
may be due to precision issues in the map file we use.  I'll look into
this.
