(at least not while I'm scrolling back 2000 lines in strace that i can see). If that file is indeed a wrapper like I'm thinking, just put in libXvMCNVIDIA.so into /etc/X11/XvMCConfig, and you will know for a fact that the right library is getting loaded. Usually to get my XvMC to work, I have to just restart mythfrontend's playback of a recording 8 or 9 times, and then it seems to start to work XvMC wise for a couple of recordings before needing to repeat. _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
