Mplayer - Illegal instruction

I've installed Mplayer in DSL from a .dsl-file.
When I try starting it nothing happens. I've also tried starting it from the terminal, and then I only get the message: "Illegal instruction" and nothing further happens.

What could this mean, and how do I solve the problem?

It probably yet another one of it's bugs, sadly it happens every now and then, try uppgrading to a newer version or upgrade the codecs and see if that helps.

ok, thanks. I'll try that.
