A parse time of 0 seconds suggests to me that POV isn't parsing 1.3Gb of
data. Even on a pretty fast machine, POV should take quite a while to
perform the parsing of anything that big. 

Rather than looking at just the timings, take a look at the "Scene
Statistics" to see how many objects POV thinks there are in the scene.
If it says there are 0 finite objects, then it didn't find your
molecules. If is says there are 0 light sources then your scene appears
may empty because you can't see anything in the dark. Another
possibility (of many) is that VMD might not have pointed the camera
towards the molecules.
