New description:

 when displaying the program guide on OS X,
 the live tv preview window is merely offset but not scaled

 the embedded window is shown at the size of the display, so it overlaps
 the guide and runs past the edge of the screen
 it looks like the mainwindow viewport is resized instead for some reason

 DEBUG OUTPUT: (using  -v most)

Comment:

 One month? That's nothing. The embedded TV window has been broken in one
 way or another since the start of the OS X port (thats late 2004). I don't
 use that feature. Note that assigning it to someone can often mean it is
 ignored for longer because other devs think "OK, Nigel is dealing with
 that one!"

 Anyway, in trunk, the embedded window scales OK if Live TV is configured
 to start in the guide, but the guide is never displayed (probably because
 the clipping region is the size of the entire window?). After exiting the
 guide, the small embedded window area remains. If normal LiveTV is
 started, and the EPG is enabled, the window never scales down, and then
 the TV image stays in the window (''i.e.'' the menu is never displayed
 after exiting TV). I will examine fixes when I have time (this is a busy
 few months for me)
