<font face="Helvetica, Arial, sans-serif">My machine:<br>
<br>
Intel Quad Core (Q6600)<br>
Asus P5N32-Plus MB<br>
EVGA GeForce 6200-LE<br>
Hauppauge PVR-250<br>
<br>
My video card is connected to my monitor via the VGA port and to my
TV. The TV connection is S-video out to an RF Modulator to my TV's
cable input.<br>
<br>
The quality of video captured via the PVR-250 isn't what I'd hoped
for. I thought at first that the video card or the connection to my TV
had been the problem, but that isn't the case. I've watched DVDs and
AVIs on the machine via the same video connection to my TV and the
images are sharp and clean.<br>
<br>
However when I capture video and replay it, it is grainy at best. When
the image changes rapidly, I get what I can only hope to describe as
problems with refresh timing; I see this big horizontal lines where it
looks like the image was painted to a certain point and then repainted
again before it finished. It's worse with high-contrast, fast action.<br>
<br>
I suspect I need to tweak the capture settings, but I'm curious what
the best values are. I tried using the settings from the Wiki
(<a class="moz-txt-link-freetext" href="http://www.mythtv.org/wiki/index.php/Recording_Parameters">http://www.mythtv.org/wiki/index.php/Recording_Parameters</a>), but those
don't seem to be getting me where I'd hoped to be. <br>
<br>
At the very least, shouldn't I be able to get the quality I see when I
hook my TV directly to the satellite STB or to the output from my TiVo
(Are these TiVo values accurate? <a class="moz-txt-link-freetext" href="http://alfter.us/tivo2svcd.shtml">http://alfter.us/tivo2svcd.shtml</a>?)<br>
<br>
Setting the resolution to anything higher than width of 480 seems to
have no effect. Myth won't let me change height above 480. I</font><font
face="Helvetica, Arial, sans-serif"> got a bit lost the settings for
bitrate etc.. Not sure if bitrate is avg or min or both, and not
sure if Myth uses VBR or CBR. From what I've read avg bitrate should
be set below max bitrate, but I'm not getting good results trying to
tweak on my own.<br>
