I have previously been able to add raster data in the jp2 format to QGIS. I am able to do so on 1.8 installed on my laptop. Unfortunately when I attempt to do this on my desktop, it claims that the file type is unsupported. I installed using the OsGeo installer.
I think I may have missed a setting on the advanced install?

ECW support (which includes JP2) is available in QGIS Lisboa standalone, but not in OSGEo4w anymore due to license issues. You can still use the standalone version, or install ECW support seperately with gdal latest builds from http://www.gisinternals.com/sdk/
I prefer the zipped version, un zipped in a separated directory. Start Sdkshell.bat to set the environment, then type
gdal_translate -of GTIFF <source>.jp2 <target>.tifto transform the image to a format QGIS can handle easily.Sample jp2 files can be found at ftp://ftp.kymartian.ky.gov/FSA_NAIP_2010_1M_UTM/Imagery/
