Could use some help on removing/disabling the default player

Thanks to all on this site who helped me be able to burn/watch movies! It seems the last problem I had was due to the fact that 2 different players were trying to play a DVD at the same time…one that I opened and another that must be the default player in Win 2K. Picture was terrible and DVD drive sounded like it was chewing paper clips. I sure could use some help on removing/disabling the default player.

I’d use an excellent and free player like VLC tool.
