<br>I'm running a P4 1.8Ghz (400Mhz FSB) with 640MB of RAM on a Dell<br>Dimension 4400. I'm using a nvidia 6200 AGP based card (specifically,<br>this one:<br><a href="http://www.newegg.com/Product/Product.aspx?Item=N82E16814130233" target="_blank">http://www.newegg.com/Product/Product.aspx?Item=N82E16814130233</a>)<br>
I'm recording only mpeg2 streams from an ATSC tuner. When I try<br>to playback 1080i based recordings, I'm averaging in the mid 70%<br>range on my cpu meter as reported by top and about every 5 seconds,<br>the video stutters. Based on what I've heard on this list, this<br>
sounds like this card should be able to offload some of that cpu<br>and that maybe I don't have XvMC set up correctly.<br><br>I'm pretty sure I followed all the instructions at<br><a href="http://www.mythtv.org/wiki/index.php/XvMC" target="_blank">http://www.mythtv.org/wiki/index.php/XvMC</a>.<br>

<div>Also make sure you have the Composite extension disabled (double check the XvMC page as I'm sure it mentions this)</div>
