<div>Pentium 4 3Ghz</div>
<div>NOVA-T 500 tuner card</div>
<div>Unfortunately no PCIe slot so I can't put in a VDPAU capable card</div>
<div> </div>
<div>Frontend:</div>
<div>ASUS M3N-HDMI motherboard</div>
<div>Athlon 6000 (dual core) CPU</div>
<div>Built in NVIDIA 8300 graphics</div><br>Both running Mythbuntu 8.10 with JYA's repositories<br><br><br> Here are the symptoms - on the Frontend.<br><br>Non VDPAU playback profile.<br><br>No problem with TV1 and TV2 playback in fact a recording that shows pixelation when using VDPAU does not have any pixelation during playback with this profile.<br>TV1 and TV2 (720p) playback has CPU usage around 62% but sometime over 90%<br>TV3 (1080i) playback has CPU usage over 100% and stutters<br><br>With VDPAU<br>TV1 and TV2 show pixelation with panning shots and fast motion<br>TV3 shows fine no pixelation<br><br>OK so I have 2 possible solutions:<br><br>1 change the settings so that VDPAU works for 720p content - I think the only option I have is to change the deinterlacer. I have tried every deinterlacer and that did not help <br><br>2 use a profile that is non VDPAU for 720p and below and VDPAU for above. This is working OK but I would really like to get
my CPU usage down.<br><br>So in summary if anyone has any clever ideas for improving VDPAU performance with 720p content i would love to hear it.<br><br> <br></div></div></div><br>
