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><BR><BR><BR><BR></FONT><FONT
