Hello, someone on IRC has pointed me to a .nuv file that doesn't play in mplayer-svn (but works with the ancient version: MPlayer 1.0rc2-4.2.3 (C) 2000-2007 MPlayer Team). You can get the file here: wget http://fs09n4.sendspace.com/dl/8f61595c0079c5e005a6ccc4f5102e6c/4c0a5c164df30f26/oxtrvk/crystal003split.nuv Here is the output of "mplayer -v crystal003split.nuv": http://paste.ubuntu.com/445147/ Basically mplayer hangs and you have to terminate it with ctrl-c. The interesting thing is, every frame seems to last 33.3 second (and the fps is exactly 33.3). I was able to dump the video frames using "-vo png -benchmark". Thank you. Giorgio Vazzana
