I get: $ youtube-dl -F http://www.youtube.com/watch?v=30ifeJZSQ64 Available formats: 35 : flv [480x854] 44 : webm [480x854] 34 : flv [360x640] 18 : mp4 [360x640] 43 : webm [360x640] 5 : flv [240x400] 17 : mp4 [144x176] I tried downloading the format 18 and the 44 and they both play fine in my machine. About your gnome-mplayer log, the curious thing is that is doesn't detect any audio stream at all. I'm using mplayer2, and I get all the audio information without problem: $ mplayer --identify --frames=0 video.mp4 ... ID_AUDIO_ID=0 ID_AID_0_LANG=und [lavf] stream 1: audio (aac), -aid 0, -alang und ... And about your VLC log, I think that more relevant than the "unknown box type tft" are the lines: 5. [0xb6a062e8] mp4 stream warning: unknown box type sidx (incompletely loaded) 6. 7. [about 200 times the line above] My guess is that your file is simply corrupted. You can try downloading it again, but my advice is to use the excellent tool "youtube-dl". -- Rodrigo
