first I had tried putting a dvd movie in the drive. Totem started, I had sound, but only the BLUE screen.
I searched around a lot ( no solution found) but there was mentioned I'd twiggle with the multimedia selector.
Had to make it available in the menu first.
Got the settings: it only works on X Windows system (No Xv). That way the testsceen shows up ok. The other options keep a dark green screen where nothing happens.
now, I got that screen in Totem too. When playing DVD's.
Same issue with playing ASF files and with VLC and also with MPlayer.
Didn't try any other formats, but I think I have to look for a solution somewhere else.
Anyone has a clue?
