Comment 4 for bug 582523

For this Xorg.0.log, I did the following:
I ran

"mplayer tv://32 -tv device=/dev/video0:driver=v4l2:chanlist=us-cable:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:norm=NTSC-M"

got black window, and noise for sound.

I stopped mythbackend, then ran

"mplayer tv://32 -tv device=/dev/video0:driver=v4l2:chanlist=us-cable:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:norm=NTSC-M"

got black window and noise for sound

I ran "testscript2" which contains:

#!/bin/sh
#
# unload hdtv wonder modules
#
/sbin/modprobe -r cx8800
/sbin/modprobe -r cx88_dvb
/sbin/modprobe -r nxt200x
/usr/bin/pkill pulseaudio; /sbin/modprobe -r cx88_alsa
/sbin/modprobe -r tuner
/sbin/modprobe -r tuner_simple
/sbin/modprobe -r tuner_types
/sbin/modprobe -r tda9887
/sbin/modprobe -r tda8290
#
# reload hdtv wonder modules
#
/sbin/modprobe cx88_dvb
/sbin/modprobe cx8800 video_nr=1 vbi_nr=1
/sbin/modprobe cx88_alsa index=1

Then ran

"mplayer tv://32 -tv device=/dev/video1:driver=v4l2:chanlist=us-cable:alsa:adevice=hw.1,0:amode=1:audiorate=48000:forceaudio:volume=100:immediatemode=0:norm=NTSC-M"

Got a video window with video and sound to match.

I exited "MythTV Backend Setup" which restarted mythbackend

I ran mythfrontend and started liveTV. I switched to the analog TV tuner, got video for about 1 second, the picture froze for several seconds and went black.
I changed channels, I again got picture for about a second before it froze for about a second then went black.
I changed channels again, I again got picture for about a second, it froze for about a second, then started flickering.
I exited live TV, and exited mythfrontend.
