The EPGImporter you installed was built for the OpenPLi 4.0 (as you had described), and is different from the one built-in the OpenPLi 7.2star. We done an update to allow the xz to work.

See with xz compatibility : http://www.ourdreambox.com/ubbthreads.php?ubb=showflat&Number=14959#Post14959

I don't know if the newer EPGImport, that is compiled with every new images, that comes from the Git of EPGImport, is backward compatible... as you seen they obliged everybody to use the xz format, and older versions were not working anymore.

You can just copy the folder from the Plugin of the OpenPL 7.2star image for the EPGImport and try to use it on an older image, if it works then you will have the solution to import it and not be obliged to upgrade to the latest version of the OpenPLi.

OpenATV 6.3 is like an OpenPLi 7.2star, same generation... on an OpenPLi 4.0, I cannot guarantee it will work. Try on a DM800HDse, and let us know how it goes. You can try the one of OpenATV 6.3 and then the one of OpenPLi 7.2star. Depending of the errors you could have, we could find out what is good and what is not.

P.S.: The ones on the JAM on OpenPLi 4.0 are v4.0, and most probably at the best with the zx compatibilty. It's just better to do as explained on the topic above, or copy from the plugin directories from OpenATV or OpenPLi the files to see if these work. Remember xz MUST be installed to have EPGImport working.
