nothing really changes
this seems to have bitten me again

when in the epg, the video preview is displayed.
when i go back into livetv. only that portion of the screen which 
contained the video preview is displaying a picture
the rest is black.

i realise that this has been caused by my fiddling. i upgraded to xorg 
1.5.3 etc. and changed my display driver to the radeon driver (from the 
ati one)
i gone back to the ati driver and the problem persists. this is annoying.

in trying to understand what is going on i have been reading the code.

one question:

i see in guidgrid.cpp the set up of a clipping region with setMask
i don't see this cleared anywhere.

what am i not getting?
