What does the attached error message mean?

I downloaded and installed SMPlayer, but get the attached error message every time I launch it in LM 10 Main. Anyone know how to fix this? Thanks.

SMPlayer is just an optional gui interface to MPlayer, and on first run just needs to be told what release of MPlayer you have installed.
Just select the option and that says something like 'r3 or newer' and that's all you need to do to start using SMPlayer.

I always just click OK and works fine
