I use BSplayer 2.63 and windows7.
I had a message from BS that a codec is needed in order to play a video and I did the istallation. I don't remember the name of the codec, but since then I can't play mp4 videos because BS reads them as sound files.
I have unistalled and install the programm many times but the problem stays.
Also, when I open BSplayer I see this error: "can't save configuration file! please reinstall with default settings or choose folder with write permission."
