Are you asking where in the source code the on screen display is? I  
know the osd* files in mythtv/libs/libmythtv have everything you need  
to make the on screen display work and guidegrid.h file in mythtv/libs/ 
libmythtv has everything needed to display the electronic program guide.

You are mistaken. MythTV uses its own internal player as its default  
video player.

No, like everything else it is built in. Luckily you have access to  
this and all of the source code.

P.S. I'm neither a developer nor am I "pretending to be one". I just  
used grep to look through the source code.
