In January 2004 the open-sourceMPlayer project accused the then Danish DVD player manufacturer, Kiss Technology, of marketing DVD players with firmware that included parts of MPlayer's GPL Licensed code. The implication was that Kiss was violating the GPL License, since Kiss did not release its firmware under the GPL license. The response from the managing director of Kiss, Peter Wilmar Christensen, offered as explanation of the similarities that the MPlayer team had in fact used code stolen from Kiss's firmware, while the release timeline of MPlayer and Kiss firmware does not support such a statement.
