Would a NVidia 7600 do, or the new Intel GMA X3000. Some new intel boards are gonna be coming out with integrated hdmi out (powered by an intel gpu, acclaiming DirectX 10 compatability (not that I care about that, just the performance)). Don't know whether it is just a modified X3000, or actually a new chip altogether. It's the 'bearlake' chipset (review of one of the non hdmi boards here:
<a href="http://www.engadget.com/2007/05/22/intels-p35-bearlake-chipset-gets-benchmarked-reviewed/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.engadget.com/2007/05/22/intels-p35-bearlake-chipset-gets-benchmarked-reviewed/
</a>).<br><br>Hopefully the boards will have good linux support, including the graphics, which means that 1080i over 1080i DVI/HDMI will actually be possible, and if the gpu is powerful enough full opengl playback may be possible.
</div></div></blockquote><div><br>Just to add to my email above, for example is there a card available that could handle 1080i with BOB deinterlacing using the opengl renderer. Also, what limits do you think a 7600GT could handle (resolution, deinterlacing methods). If yu don't know no problems, just you are the first person I know who's actually used it.
<br><br>Also, using the opengl renderer (which I like the look of). Is is possible to playback (ignoring current performance limitations) interlaced material over an interlaced connection properly (e.g. 1080i on 1080i), is it actually capable of syncing to the right phase (
i.e. even w/ even, and odd w/ odd)?<br><br>Sorry for all the questions, just I'm deeply interested in the opengl rendering (the benefits look good, and not many negatives apart from card requirements).<br><br>Thanks in advance, James
