have a couple blocks of channels that are snow. most channels work OK,
however.
<br>
<br>
Details:
<br>
analog cable input on PVR-350 card (Time Warner in Minneapolis, MN)
<br>
slowish PC - P-450 with 256MB RAM
<br>
KnoppMyth install R5V22
<br>
<br>
Channels channels 2-13 come in fine
<br>
Channels 14-20 are snow
<br>
Channels 21-36 come in fine
<br>
Channels 37-60 are snow
<br>
and lastly, Channels 60+ are OK.
<br>
<br>
In mythtv-setup, I've tried changing the Cable system from 'Default' to
'US' to 'US-HRC' and 'Broadcast' with no change (actually my box locked
up when it was set to 'Broadcast' - still same snow seen.
<br>
<br>
I've tried fine-tuning a couple channels (though I really don't know
what I'm doing) and did get different looking snow (squggly lines,
black bands, etc) but nothing anywhere near resembling a picture. The
way I changed the tuning was in MythWeb, where I changed the setting
(from 0-600 in increments of 50) and saved it, then changed the
channel, then back to the one I fine-tuned. <br>
The channels that come in look good. The TV can tune in ALL the
channels fine, Myth can not.

<br>
I don't know what to do. I'm definitely NOT a myth or linux expert...
I've searched the KnoppMyth forum, the mythtv-user archives and google
with no help on this exact type of problem.
<br>
<br>
Suggestions?
