[mythtv] DVD Menus and Screensaver

[Bill]

I would like to make patch to enable the screensaver while in a dvd menu 
when playing a DVD or DVD ISO to avoid screen burn.  I am looking for some 
tips of where to incorporate this, particularily tips that will maximize the 
chances the mythtv-devs would incorporate it to SVN.  I can see in 
tv_play.cpp how the screensaver is enabled and disabled for things like 
pausing the video.  I assume that the function DVD()->IsInMenu() could be 
used to detect when in a DVD menu for the purpose of knowing when to enable 
the screensaver.  The proposed patch would then have to periodically call 
the IsInMenu function and enable the screensaver in this case, then disable 
it once out of the menu.

Where would the best place to put this such that it would be accepted by the 
myth devs into SVN?

Any tips on implementation?

Thanks in advance.
