</div></div>Well I might be getting somewhere. I tried a lot of things and the<br>
best I came up with is:<br>
NvAGP = 1<br>
disable composite (helped a lot)<br>
change the xvmc library in XvMCConfig to the nvidia wrapper<br>
and now I get playback that isn't choppy but is totally motion blurred<br>
like Bob isn't deinterlacing. I tried the other one but my<br>
understanding is that it isn't supported in xvmc. Am I crazy or didn't<br>
there used to be other methods (kernel comes to mind)? I ran with -v<br>
playback and I don't see any bob deint failure lines. I'm running the<br>
frontend at HD576i (I have a 4:3 CRT HDTV that looks awful @ HD1080i -<br>
apparently nvidia's fault according to the internets so I run it at<br>
this res with a virtual resolution of 1024x768) but if I up it to<br>
1080i the motion blurring goes away (but its crazy ugly due to my<br>
crappy TV and stretched because its a 4:3 TV). I tried setting a<br>
modeline for a virtual resolution of 1440x1080 but it didn't work,<br>
although I'm not really sure if I did it right.<br>
Anyway I'll try with the envy drivers to see if that fixes the<br>
deinterlacing problem.<br>
<br></blockquote><div>I've been using the nvidia 5200 (fanless) for almost two years with a 3 gh intel processor. I can record one HD channel and watch another HD channel one at the same time without a problem.<br><br>
