problem with bsplayer

hi, I have a big problem with bsplayer.

I went to mpeg codec properties, and set the colour to B/W (just to experiment), and since that, I can´t open any MPEG with bsplayer, but on the other hand, I can open avi files and looks ok. When I use windows media player to see the MPEG files, they are in B/W, but I can´t change back the way the codec works, because I can´t play the file with bsplayer !!! :shock: :(

is any way to change the mpeg codec to put it back to colour, or at least open the files with bsplayer again to do it ? thx a lot
