In my case the "ghosting" is a constant element.<br><br>It does vary depending on the brightness and complexity of the background wall but it doesn't matter if I'm on LiveTV, high quality or low quality and getting in and out doesn't change a thing...

<div><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;">ok, I am seeing exactly the same thing but with WinTV PVR USB2.
<br><br>If I press 'esc' and 'enter' in mythtv livetv, the image becomes
cleaner: no ghost. I change channel from 3 (nbc) to 2 (fox) and back,
and I see ghost on the "Medium" night scene on nbc. I 'esc' and 'enter'
quickly, the same scene is now clean. I repeated this many times to
verify this behavior and it worked most of the times. The behavior has
some uncanny similarity with the other video related problem, which I
think is pvrusb2 specific: the upper 10-20% of the screen gets
garbled while changing channels sometimes, and 'esc' followed by
'enter' solves it most of the times.<br><br>Once I exit 'livetv', the ghost goes away
and mplayer /dev/video0 doesn't show it. mplayer seldom shows it in
fact: so, it could just be a mythtv thing for all I know, but the fact
that the ghost gets into the recording is worrisome. It has screwed
many of my recording.<br><br>-devsk<br><br><div style="font-family: times new roman,new york,times,serif; font-size: 12pt;"><div><span class="e" id="q_1105bbbaa48a8bfe_1">----- Original Message ----<br>From: denis-carl robidoux <
