Hello,
any ideas how to make work Czech Television archive work with MPlayer?

Currently when I go to the site, MPlayer starts but no video starts playing. You can try e.g. http://www.ceskatelevize.cz/ivysilani/20856226710-tak-se-tanci-tango-argentino-v-praze/

You can use ‘Nízká kvalita’, ‘Střední kvalita’ and ‘TV kvalita’ links to change the resolution of the video. Sometimes it works/worked in Quick Time Player with Flip4Mac WMV decoder, I guess Real Player would also work, but I'd prefer WMV streams in MPlayer.
