I've been playing with EyeTV to compare video output quality with MythTV, and also look at CPU load. The EyeTV H.264 codes does utilise both core's in the MacBook which is good as on TVOne/2 it can use over 70% on both cores, and TV3 well over 80% of both cores. Hence my assumption is that their decoder is currently software based.</div><div><br></div><div>I tried exporting a recording into a file format that Quicktime supports to see if it will do HW acceleration, but I just get a green video window.</div><div><br></div><div>Steve</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>
