Depends on the player. If the input of the player is S-Video and it will convert that signal, then it will work; however, sometimes companies get lazy and make electronics without converters (ie, the S-vid in goes only to s-vid out). Just give it a try, in all likely hood it will work.
If you installed the drivers that came with your card, it is usually pretty easy to either switch between monitors, make the TV a clone, or make the TV a second desktop - keep in mind that if it\'s a regular TV you will be in 800x600 or 640x480 without stretching/compressing things.
