I'm not sure how that would help you, except for the list of enabled useflags:

mplayer (I tried mplayer2 a longer while ago, but went back very quickly).

> Do you use ffmpeg or libav?

According to the output, it's libav.

I asked a friend with Gentoo to play the video -- it works fine for him.
Because he is using Core i5 graphics, I got a hunch that nvidia might be the
culprit, so I booted my nouveau setup (kernel.org sources version 3.5.3). Now
I'm getting some more output (and a different error). It's not really helpful,
but here goes:


*** glibc detected *** mplayer: free(): invalid next size (normal): 0x000000000150a3d0 ***
