I'll take the other side of this coin, just for a moment. I can understand WANTING to include the default/built-in player for this reason, there will be people that don't want to configure multiple pieces of software, just load XLobby, play music, watch vids, see the weather, etc. They want a simple, clean, MINIMAL configuration approach to this.
The option DOES need to be in there to switch the internal players (Vid, Aud, Both) off easily for those of us that DO want to use external players.
Just my 2 cents
