[mythtv-users] Can't find "Player Settings"

[Sergio Bello]

Hi all,
I've read about the possibility of using an external player like mplayer 
instead of MythTV internal player. As documentation says: "you will need 
to delve into your MythVideo **setup.At the main screen, scroll down to 
Setup, then Video Settings, then Player Settings". But I can't find nor 
MythVideo setup nor any "Video Settings" or "Player Settings" option in 
MythTV frontend. I've installed MythTV 0.21 on Ubuntu from Sypnatic 
manager, and I've installed mythvideo and mythplugins too.
Where is Mythvideo setup?
Thanks a lot
