my first point is that tvtime is a nice tv application, that uses xv.
my second is that tvtime does not work with dvb-t adapters that sent a mpeg2 
stream to the tv application - which most dvb-t adapters do.

if you think your load is too high, try opengl, sdl, xvmc as 'video driver' 
instead of xshm.
