[vdr] softdevice g450 tvout, high cpu utilization?

Is there anyway to lower cpu usage on G450 w/ vdr/softdevice? At the moment
it uses about 27%+ cpu constantly on my system, is it normal? I've tried ATI
7000 LE, w/ gatos/XORG/xv and it was using only 17% but picture and OSD is
much worse than G450s.

Just some indirectly related questions.
Is hardware acceleration supported on g450 TV-out at all with this setup?

Is g400 would work better than g450?

Are there any start up parameters can be passed to kernel so second
head(tvout) would run in NTSC mode?

Thanks in advance,
