I got this update courtesy of openVix support site. It updates a .xml file to allow correct insertion of Premier Sports HD & Setanta Sports 1 HD.
This update is only for those using OpenVix Hades 18 or less. Apparently new OpenVix releases after this current release will feature the updated file.
This plugin should work on most, if not all, Enigma2 boxes running recent OpenVis Hades image 18 or less although I can't confirm this. I don't think this plugin would work on really old image series like Apollo, etc.
