I had a poke around the screensaver code, and can see how the 
screensaver is enable and disabled.   But I'm not sure how the display 
is re-enabled when the remote is pressed.  Is X supposed to handle 
this?   If so, what would stop the remote from re-enabling the display 
in mythwelcome ... when it works ok on mythfront end.

PS:  Nothing else has changed on the system ... I only upgraded from an 
early December trunk to the current trunk.
