<div>Sounds to me like there's a great demand for Dual PPC with Altivec optimization here...</div>
<div> </div>
<div>:)</div>
<div> </div>
<div>Thanks for the note Tim, I'll be sure to get that updated when I get homew tonight. Meanwhile - I'll be looking on the Apple pages for help with Altivec, from my initial research there seems to be a lot there.</div>
<div> </div>
<div>H.264 on Quicktime is very slow - but I haven't compared it to x264 yet. Anyone know how well the Intels are doing with regards to 1080p? Seems they can do SD to at least 25FPS.</div>

<div>Thanks,</div>
