Change Default Video Player in MythTV

To change the default player for video playback in MythTV, enter the "Main Menu", then select "Utilities / Setup " --> "Setup" --> "Media Settings" --> "Videos Settings" --> "Player Settings", input your preferred video player in the filed "Default Player". For example, if your preferred play is "mplayer", you can input "mplayer %s -fs -zoom", where %s represents the path name of the current directory (including the vidoe filename).

In order to use a P2P streaming software to play movie in MythTV, I create a perl script "moiveplay.pl". Then I input in the field "Default Player" "/home/mythtv/movieplay.pl %s". Thus when I select a title in MythTv, the P2P streaming software will run and play the movie.
