They are running a regional version of the UK Met Office > Unified Model. Looks like another grib(1) idiom.

I took a look at the data and am guessing that it's U & V winds. I made a table following the guidelines at: http://www.unidata.ucar.edu/software/IDV/docs/userguide/data/GribTables.html The attached plugin has the grib1tablelookup.lst and a fabricated file for the two parameters (201, 202). Grib parameters higher than 128 are center specific. I tried using an ECMWF table, but in there, the parameters were max/min temps. If your colleague could supply the real grib table to us, we could add it into the distribution. I looked on the South African Weather Service web site, but couldn't even find a place to do a search. Anyway, install the attached plugin and that will at least allow you to plot the sample file you gave me (assuming they are u and v winds).
