The problem is that you are running out of memory. These are huge images. NMAP uses the X-Server to do the decimation of the images, IDV does not. In either case, you'll need to subset the data before loading or have the IDV resample before the display. From the Image Chooser, you can subset the data over a particular lat/lon. From disk, your only option at present is to set the Max Image Size preference (under the Formats & Data tab of the Preferences) to be something like 1000000 (1 meg-pixel) so the IDV will pre-decimate the image. If you want to load only a small region of the 1km data, then use the Image Chooser to subset to the region you want to display.
