It is interesting though that in my account I see this notice as mplayer is starting up: Opening video decoder: [ffmpeg] FFmpeg's libavcodec codec family libavcodec version 53.35.0 (external) Mismatching header version 53.32.2 Selected video codec: [ffh264] vfm: ffmpeg (FFmpeg H.264) I never noticed this before, but when it was working, I didn't look, either. Also, not in my account but another, there are X11 errors for an integer value out of range when I go to full screen, but not if the scale is left alone. I don't remember seeing this before, either. </pre> <blockquote type="cite"> <pre wrap="">Also, if you run vlc -v, does it give you any errors in the terminal? </pre> </blockquote> <pre wrap=""> Yes, many, usually having to do with oddities in the video, but they're all coming out completely blank. One of the reasons I used VLC at all was that it had better recovery from video glitches than other players. I'm thinking one of my video drivers or codecs is failing where it didn't before, but I have reinstalled everything and they're still not behaving as before. </pre> </blockquote> What graphics card driver do you have? (run sudo lscpi or sudo lshw -c html > hw.htm if you don't know). If it is a proprietary one then that can often cause problems (e.g. NVIDIA or old ATI). What errors does VLC/mplayer give exactly? Mplayer errors can be turned to very verbose by running mplayer -msglevel all=9. Vlc should also output some error/warning messages. Joshua </body> </html>
