I'm not sure what you mean. dispcal uses software generated patch values, so (by definition) they can't be burnt to DVD. displread uses a pre-set series of patches, but they are in the .ti1 file, and quite accessible. Note the utility filmtarg (not currently compiled by default) creates a series of rasters with patch values from a .ti1 file. Graeme Gill.
