Hi, I've been running 0.24 until this week. With 0.24, I followed the wiki on <a href="http://www.mythtv.org/wiki/User_Manual:JudderFree">http://www.mythtv.org/wiki/User_Manual:JudderFree</a> and got judder-free working just fine.<div>
<br></div><div>Then I updated my system completely (Gentoo x86_64):</div><div>Kernel 3.1.10->3.5.7</div><div>nVidia 295.75->304.64</div><div>Mythtv 0.24->0.26</div><div><br></div><div>...and everything in between.</div>
<div><br></div><div>Now when MythTV is running, it doesn't properly change the refresh rate.</div><div>When the system boots up, it's at 60 Hz (TV reports 1080/60p). Now, if I play almost ANY video (24fps movie or regular cable), the refresh rate is set to 30 (29.975 I guess, my TV just reports 1080i, it's the 30.0 mode w/an * in xrandr below). Exiting the video doesn't restore the 60p either.</div>
<div><br></div><div>Now, I know I have most of the settings still configured correctly, at least outside of Myth, because I can change the refresh manually with xrandr and it works (TV changes what it reports), plus XBMC on the same machine also switches correctly.</div>
<div><br></div><div>So what changed in MythTV?</div><div>I verified the checkbox for 'Separate GUI and Video Modes' is still checked, and refresh rate is set to 'Any'. I also toggled it off and back on again, just to make sure.</div>
<div><br></div><div>I did notice a couple of things though:</div><div>I have one video which is actually 25, and it changes the refresh to 60 Hz. (again, TV reports 1080/60p)</div><div>When changing the resolution with xrandr, I can't use the modes listed, I have to use the nvidia ones (??), for example:</div>
<div>To set 1080/24p, I have to execute <font face="courier new, monospace">xrandr -r 58</font></div><div><br></div><div>I supplied xrandr output, xorg.conf and mythfrontend log. I have the xorg.log as well, but it's large so I didn't know if I should attach it or not.</div>
