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, --Vlad

No idea, I use graphtft in fb-mode (which also consumes high amounts of cpu (up to 90% when playing movies as it updates the screen every second).

As far as I undestood the various readmes there is no hardware acceleration on 2nd port (which is the tv.out port).

You can use matroxset to change this setting (and also some more ;) ). Useful links for g450 tv-out:
