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;">----- Original Message ----<br>From: denis-carl robidoux <deniscarl@gmail.com><br>To: Discussion about mythtv <mythtv-users@mythtv.org><br>Sent: Thursday, January 25, 2007 3:49:10 PM<br>Subject: Re: [mythtv-users] Ghost image on my PVR-350<br><br>v4l2-ctl is installed with my new version of MythDora but it does not support any command that look close to dnr_mode, dnr_spatial or (the most important if I understand what I read yesterday) dnr_temporal<br><br>So, I'm still stuck with ghosts... let me show you:
