For TV3 above I get 88% on one core and 29% on the second core with Bob. Without a de-interlacer almost all the load is on one cpu.</div><div><br></div><div>There doesn't appear to be much of a performance difference between playing AC3 or AAC on TV 3 which is good news.</div><div><br></div><div>So the niggles</div><div>1. The X2 6000+ is a 89W CPU part so the core is hotter and the fan faster than I'd prefer. There are rumours of some lower power parts, but they might only work in AM2+ compatible boards.</div><div><br></div><div>2. Occasionally I get a picture in picture effect when I switch between 720p and 1080i channels which I have two copies of the same video feed on screen, one of which is in a small box in the top left hand of the screen.</div><div><br></div><div>3. The AAC audio doesn't always lock on a channel change</div><div><br></div><div>So I have something that works, but I wouldn't consider it customer ready.</div><div><br></div><div>I think I need to consider an Intel compatible alternative, but can't find a board with integrated Composite/Component/SVideo as well as DVI/HDMI in the Intel space.</div><div><br></div></div></blockquote><br></div><div>Turned CPU scaling back on which is rather interesting</div><div><br></div><div>For 720p channels it is happy to peg the cpu at 1.8 GHz, for 1080i it goes all the way upto 3.1 GHz.. The SD channels go all the way down to 1GHz which is the lowest speed setting.</div><div><br></div><div>Going to leave the box playing TV3 for a couple of hours and see how it copes with the load.</div><div><br></div><div>Steve</div><div><br></div><br><div> <span class="Apple-style-span" style="border-collapse: separate; color: rgb(0, 0, 0); font-family: Helvetica; font-size: 12px; font-style: normal; font-variant: normal; font-weight: normal; letter-spacing: normal; line-height: normal; orphans: 2; text-align: auto; text-indent: 0px; text-transform: none; white-space: normal; widows: 2; word-spacing: 0px; -webkit-border-horizontal-spacing: 0px; -webkit-border-vertical-spacing: 0px; -webkit-text-decorations-in-effect: none; -webkit-text-size-adjust: auto; -webkit-text-stroke-width: 0; "><div style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>Steven Ellis - Technical Director<br>OpenMedia Limited<br>email - <a href="mailto:steven@openmedia.co.nz">steven@openmedia.co.nz</a><br>website - <a href="http://www.openmedia.co.nz/">http://www.openmedia.co.nz</a><br></div></div></span> </div><br></body></html>
