font-family:Arial'>I am running Mythtv 0.20.2 with ivtv 1.0.3-r1 on a Gentoo
machine with a 2.6.22 kernel. I am using a PVR-350 with a LG tuner
on it, and am having pretty good success with the exception of a herring bone
patter on some channels and a picture that is also somewhat “grainy.”
Both of these problems vary across the channels, but the worst channels for the
herringbone problem are the low channels (those below 10). In any case, I
was doing some looking and it appeared that some people were using the special_filter
and temporal_filter options on the Hauppauge card to minimize the
problem. I have run the temporal_filter parameter from 0 to 31 with the
temporal_filter_mode set at both 0 and 1 and it seems to make no difference in
the picture. I have tried similar things with the spatial_filter.
Is there something that has to be done to turn on these filters? The
settings that I change are visible with the v4l2-ctl –l command, they
just do not seem to change the picture any. <o:p></o:p></span></font></p>

font-family:Arial'>BTW: I also tried a isolation transformer to try and
get rid of the interference pattern, and that did not help at all. I’ve
also ordered a cable amplifier to see if that helps either of these
problems. Unfortunately, I do not have another Hauppauge card to make
certain it is not just the card. <o:p></o:p></span></font></p>
