Rigol wmf file format

[aroby]

I'm trying to get the wfm_viewer application (http://meteleskublesku.cz/wfm_view/) working with my DS2072A.  It kind of works, but complains that the trigger mode is not recognized.  I have also tried the Python code (https://github.com/mabl/pyRigolWFM/blob/master/wfmutil.py) that was sourced from the parser for wfm_viewer, but that can't process my file - seems that the header on the file has changed signficantly.

Has anyone come across documentation for the wfm format Rigol are using or have a working parser for the DS2072A?
