I want to let everyone know that I have no problems viewing HD with XVMC. I have an AMD Athlon XP 2500, 1 Gig ram, Nvidia FX5500. I had HD going smoothly for about 7 months but at some point last summer, I experienced some issues after upgrading either kernel, nvidia drivers, myth, I can't recall, but from memory, here's what I checked before determining that /etc/X11/XvMCConfig needed to be properly tweaked:<br><br>- Since I use Gentoo, ensured that xvmc was in my USE flags<br>- Made certain X was using the nvidia driver and not the default nv driver in xorg.conf<br>- In an xterm session, checked my X server had xvmc enabled (xdpyinfo and look for XVideoMotionCompensation in the list of supported extensions<br>- Review /var/log/Xorg.0.log for errors (or maybe did a startx and redirected to a file)<br>- Review mythfrontend console window output.<br>- In one of these hunting expeditions, I saw an error about xvmc libraries so I was now onto something.<br><br>In the
end, I had just about everything set up (including enabling XvMC in mythfrontend). The only thing I did was to create the file /etc/X11/XvMCConfig which contains one line: /usr/lib/libXvMCNVIDIA_dynamic.so.1. For good measure, I rebooted my system just to make sure everything was properly re-initialized. Boom, I was able to view my HD recordings perfectly.<br><br>I hope I help steer some of you in the right direction. I share your pain.<br><br>Norm<br><br><b><i>John Welch <jrw3319@gmail.com></i></b> wrote:<blockquote class="replbq" style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; padding-left: 5px;"> Add me to the list of people having problems with HD playback.

earlier this<br>year I was able playback HD. I did have some issues, but overall it<br>was acceptable. Then I didn't do much with HD throughout the summer.<br>Now it has regressed to where I can't watch HD reliably anymore.<br>Upgrading to .20 seems to have made things worse, but I was having the<br>problems before I upgraded. I've played around with a bunch of the<br>settings (with and without XvMC, with and without audio buffering,<br>etc.) but haven't found the right combination (if there is one). With<br>different setting I get different results; choppy playback, slow<br>playback, etc., but none are acceptable.<br>_______________________________________________<br>mythtv-users mailing list<br>mythtv-users@mythtv.org<br>http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users<br></blockquote><br><p>
