I have looked at my cpu usage several times throughout the past: on 720p material I see 60-70% cpu usage; 1080i 70-80%, it might be your nvidia binary... I remember there was one nvidia release that shot CPU usage through the roof, I think it was in the 6000 series though. I update myth to SVN almost weekly, and I run aptitude/deselect almost monthly to update the rest of the software and stay on the sometimes painful cutting edge. :) <BR></BLOCKQUOTE><DIV><BR class="khtml-block-placeholder"></DIV>I just upgraded my system to a new kernel (2.6.18-1.2239.fc5) and new nvidia drivers (9631). kernel deinterlace gives me 105% on mythfronend and 25% on xorg. linear deinterlace is the same as it was before. This is the reason I ended up upgrade my AMD 64 3200+ system. I was tired of trouble-shooting XvMC and OpenGL settings to get something that worked. Now it works, just chews up all my CPU. I am using an nVidia 6600-OC card. It's PCI-Express. I just kept throwing money at the machine until I could watch HD without stuttering. My time was worth more to me than the cash I was spending on it. This is also the reason I don't run svn. I get too frustrated when things break so I'm using up to date .20 from ATrpms.</DIV><DIV><BR><BLOCKQUOTE type="cite"><BR> Are you running a FC released kernel? I'm not sure it matters but I'm using one I built from <A href="http://kernel.org">kernel.org</A> currently, 2.6.19. It's setup with exactly the drivers and options that I need. Make sure you are using nvAGP, you have to disable the agpgart in your kernel config in order for the nvidia driver to enable it's own driver. <BR><BR>-Greg<DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">_______________________________________________</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; ">mythtv-users mailing list</DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="mailto:mythtv-users@mythtv.org">mythtv-users@mythtv.org</A></DIV><DIV style="margin-top: 0px; margin-right: 0px; margin-bottom: 0px; margin-left: 0px; "><A href="http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users">http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users</A></DIV> </BLOCKQUOTE></DIV><BR></BODY></HTML>
