Hi all. This seems to be the old problem as ggogle tells a lot about this but anyways can't find the solution. The problem is: 1. I insert a DVD into the drive, I issue the command: silverdr@vessa:~$ mplayer -dvd 1 and I get the results as below. **************************************************************** Using GNU internationalization Original domain: messages Original dirname: /usr/share/locale Current domain: mplayer Current dirname: /usr/share/locale MPlayer 0.90pre10-2.95.4 (C) 2000-2002 Arpad Gereoffy (see DOCS) CPU: Advanced Micro Devices Athlon 4 PM Palomino/Athlon MP Multiprocessor/Athlon XP eXtreme Performance (Family: 6, Stepping: 2) MMX2 supported but disabled CPUflags: MMX: 1 MMX2: 0 3DNow: 1 3DNow2: 1 SSE: 1 SSE2: 0 Compiled for x86 CPU with extensions: MMX 3DNow 3DNowEx SSE Reading /home/silverdr/.mplayer/codecs.conf: can't open '/home/silverdr/.mplayer/codecs.conf': No such file or directory Reading /etc/codecs.conf: 44 audio & 110 video codecs font: can't open file: /home/silverdr/.mplayer/font/font.desc Font /usr/share/mplayer/font/font.desc loaded successfully!

The same DVD plays OK in _the same_ drive in _the same_ pc when using a windowz player... :-( 4. Some other DVDs play more or less flawlessly using mplayer. Any clues?
