Well I've gone ahead and added a signal booster on the line to the 150
and it seems to have greatly improved video quality all around. I'll
need to do some more watching, but channel 2 is the only one where the
"rolling" interference is really noticible anymore without very close
examination. I may go ahead and another 150 just to see if it has
any effect. <br>
<br>
As for that 4th 150 of yours, it appears to be the same as mine, so if
you'd like to get the tuner working at some point, adding:<br>
options ivtv tuner=50 <br>
to the modprobe.conf should do the trick. <br><br><div><span class="gmail_quote">On 4/16/06, <b class="gmail_sendername">Brian Wood</b> <<a href="mailto:beww@beww.org">beww@beww.org</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">
