Launching bsplayer by double- clicking on file problem

[ditchwater_monkey]

Whenever I double click on a video file, bsplayer player launches and displayes the following error message:

Cannot find the file '<whatever?>' (or on of its components). Make sure the path and filename are correct and that all required libraries are available.

However, the file plays fine!

can anyone explain what's going on here?

cheers
