Using the same settings on the new 16.04 install I have bad tearing when the boards pan on Jeopardy where I did not on 8.04. As far as I can tell, everything is the same. I still have the 8.04 HD, which has serious issues but will play so I am able to compare the silky smooth performance of 0.21 to the jerky performance of 0.28<br>

With Nvidia it helps to turn off composite to prevent tearing.<br>
sudo nvidia-xconfig --no-composite<br>
or else add this to your xorg.conf.<br>
Section "Extensions"<br>
Option "Composite" "Disable"<br>
EndSection<br>
<br>
Note that turning off composite prevents Ubuntu unity desktop from working. I use xubuntu to avoid that problem.<span class=""><br>

Most things are the same as described below. The differences are that I am aware of are that the new driver is 304 (which I confirmed is in use with additional-drivers) and the 8.04 system used 180.<br>
<br>
The other difference is that on the 16.04 system the nvidia-settings icon does not launch anything. It is just like clicking on air. I Googled this and found several people with the same problem and nobody with an answer. Maybe the problems are related<br>
<br>
The hardware is a M3A with AMI 5400, Geforce 6200 LE video card.<br>
<br>
I put the same xorg.conf file in /usr/share/X11/xorg.conf<br>
<br>
I created the same custom playback profile<br>
If rez > 0 0 -> ffmpeg & XVideo<br>
xv-blit softblend<br>

For general picture quality you would do better to use VDPAU slim playback profile if possible, or failing that, use OpenGL Slim.<span class=""><br>

I have dual displays only one has myth. Here is its xorg.conf section from the 2008 file I transferred over to the new disk. I rebooted after loading the xorg.conf file<br>
<br>
Section "Screen"<br>
Identifier "Screen1"<br>
Device "Videocard1"<br>
Monitor "MythMonitor"<br>
Option "TwinView" "0"<br>
Option "metamodes" "DFP: 1280x720_60 +0+0"<br>
Option "AddARGBGLXVisuals" "True"<br>
# this next line will be ignored with the TV and the default, auto will be used<br>
SubSection "Display"<br>
Depth 24<br>
EndSubSection<br>
Defaultdepth 24<br>
EndSection<br>
<br>
<br>
This list has been tremendously helpful on my other problems so I am hopeful I don't have to go back to 8.04 although at this point I can make a case for doing that.<br>
