I generally don't trust mplayer binaries because their codec sources aren't updated frequently.
I've been using mplayer2 compiled from source since the anime world started using 10bit, and it's very reliable.
Compiling it yourself would ensure no instruction set issues, which those bug reports indicate.

There is still problems with mplayer in Lubuntu: mplayer2. After 8 months, the default media player in Lubuntu 12.04 just stops. Yes, I have an old computer, that's why I use Lubuntu. Why not have vlc as the default player?

There is a fix now according to this link

See this link how to enable ''ubuntu-proposed', where you can find the new and working version of mplayer2

I hope it will soon come into the standard repo.
