It used only 5-6% of my CPU when I played 1080p movie. That sounds great but i do not have any nVidia hardware so i cannot test it myself. What configure options did you exactly add? From the VDPAU wiki page it looks like it would be a good idea to add both: --enable-xvmc-opengl --enable-vdpau I hope to have some time in the upcoming days to prepare a test port for this and will reply when i'm ready. As a side note i've seen that MythTV is already preparing a 0.23 release so I want to have a 0.23 port ready for a Call for Testers when they announce their first release candidate. -- Bernhard Fröhlich http://www.bluelife.at/
