I've recently replaced my standalone mediecenter with a<br>
frontend+backend solution.<br>
<br>
The backend is the old standalone mediecenter, and is doing a really good job.<br>
The frontend is a Asus AT5IONT-I board, with a d525 CPU and 2 x 2GB<br>
SODIMM RAM (800Mhz)<br>
<br>
Even with quite simple SD recordings, this frontend is unable to do a<br>
proper playback using VDPAU!<br>
(example recording: <a href="http://glemsom.users.anapnea.net/sd-playback.mpeg" target="_blank">http://glemsom.users.anapnea.net/sd-playback.mpeg</a>)<br>
<br>
Even with temopral x1 I get this in my log:<br>

The CPU is close to idle all the time, and I have no idea what is causing this!<br>
<br>
<br>
* Video out is through the onboard HDMI<br>
* Audio is through the onboard SPDIF<br>
* There is NO special asound configuration<br>
* Audio-upmix is disabled<br>
* VDPAU using temporal X1<br>
<br>
According to the wiki, this setup should do Advanced X2 for SD<br>
content, and Temporal X2 for HD. (<a href="http://www.mythtv.org/wiki/VDPAU" target="_blank">http://www.mythtv.org/wiki/VDPAU</a>)<br>
As described in the wiki, I've added "nvidia-settings -a<br>
'[gpu:0]/GPUPowerMizerMode=1'" to my .xinitrc, and I've disabled<br>
Composite in xorg. (with no luck)<br>
<br>
On a (unrelated) side note, I have a Windows 7 setup using the same<br>
mainboard and RAM - that that setup is with coreavc (software<br>
decoding) able to show 720p, and 1080p (if the bitrate isn't too high)<br>
<br>
<br>
System configuration:<br>
mythfrontend --version<br>

</blockquote></div><br><div>Glenn,</div><div><br></div><div>Are you connecting wirelessly? I had similar problems with my setup and it turned out to be the wifi rather than the video decode. I would copy a file to the local hard drive to test playback, or do some throughput tests using iperf.</div>
