Subject: Help w/ATSC tuner (kworld 120)
Date: Thu, 19 Mar 2009 14:11:04 -0500	[thread overview]
Message-ID: <49C298C8.3080100@xnet.com> (raw)

Hi...

I know the v4l support of (what I think is the newest) Kworld 120 is not 
100 % (for instance I don't think you can switch between NTSC and ATSC 
w/o a power cycle -or- use the remote control).  However, I had been 
using it for months for ATSC reception w/o any problems.  Then, after a 
Debinan (unstable) update, I lost the card.  I assume I had picked up a 
new release of v4l.  So I tried to re-compile & install my source copy 
of v4l I downloaded last July - but that didn't work. I then downloaded, 
compiled & installed the most recent v4l today - but that didn't work 
either.  Currently, the tuner acts as if the signal is weak.  The 
picture is pixelated and breaks up.  I have swapped the antenna lead 
with a set-top-box ATSC tuner.  The set-top-box appears to work well 
with either it's own antenna lead or the Kworld's antenna lead.

So, now I'm wondering - could something have happened to v4l in the last 
9 months?  For instance, could a v4l code change effect the Kworld 120's 
AGC feature?

FYI: The same antenna provides signals for another Kworld 110 tuner and 
a Happauge NTSC tuner (both in a different computer) as well as a number 
of other appliances.   All of which appear to be working fine.

...thanks
