second or so, particularly on horizontal pans. On HD H.264 broadcasts<br>
the judder is there, but less noticeable. I am in the UK, so these are<br>
25fps interfaced. On ripped DVDs (deinterlaced with Handbrake where<br>
applicable) at 25fps and Blurays at 23.976 fps playback is generally<br>
smooth, but there is an occasional jump. This happens on all playback<br>
profiles. The refresh rate on the TV appears to be correctly switching<br>
based on the content.<br>

"DISPLAY=:0.0 xrandr" from an SSH session - ie, with no params -<br>
during playback. The picture jerks once and then settles to be smooth.<br>
It is also fixed sometimes by returning to the playback settings menu<br>
and then starting playback again.<br></blockquote><div> <br></div></div>I suspect those to be caused by bug #12150. Running xrandr from SSH would refresh the modeline used by avsync_predictor in MythPlayer, so does my patch from this bug report.<br>
