Hi,<br>
<br>
I have mythtv running on a atom-ion box.<br>
I run the nvidia drivers and have mythtv set to use vdpau.<br>
When playing HD videos, there is quite a lot of "tearing" displayed on<br>
the screen.<br>
I tried compiling the latest git repository with the<br>
"--enable-opengl-vsync" but this does not appear to be a valid option<br>
any more.<br><br></blockquote><div><br></div></div><div>make sure this is in your xorg file</div><div><br></div><div>Section "Extensions"</div><div> Option "Composite" "Disable"</div>
<div>
EndSection</div><div><br></div><div>and as the previous email, make sure you enable vblank in the settings and save them, you then call nvidia-settings on X loading to reload the settings each time. You can add this in to the autostart etc. </div>

<br></blockquote></div><br>I had a couple of issues which caused tearing using ION Zotac front end. The composite-line fixed
the worst of it, then tuning the VDPAU and Resolution settings helped
imrpove the image quality and remove tearing which was happening due to
screen-size mismatch to desktop.<br>

See my post here, it will lead you to mythtv thread where this topic was commented on by other mythtv-ers.<br>

<br>There are log files too which may help you troubleshoot whether you have the same problem(s) or not. I updated a couple of mythtv wiki pages on the subject of tearing too with references to the the composite-fix.<br>
