Users of vdr-xine my want to try xine's stretch audio plugin. Just add

	--post stretch:factor=0.6667

to xine's command line for 1.5x speed. But maybe it's a better idea to 
add it via xine's audio post processing dialog just when watching a 
recording, as it doesn't work well when watching live TV. The satellite 
won't speed up to broadcast at 1.5x ;-)

Bye.
