Hi,
Am 13.03.2010 13:48, schrieb James Pifer:
I was having problems with some of my mythtv recordings having bad
video. The leading contender for the issue is too much stuff going on
for one hard drive. So I added a new smaller drive for the OS and also
updated to the OS to CentOS 5.4. I then installed mythtv and ivtv using
yum.
I have a PVR150/250/350.
If I try to capture video by cat /dev/video0 (or 1 or 2) all I get is a
green picture. I've gone through the troubleshooting and did not come up
with a fix.
modprobe.conf has nothing in it, but ivtv is loaded if I do an lsmod.
Anyone have any suggestions?
Have you tuned to a channel or set to an external input before the cat? I think you can use ivtv-tune or v4l2-ctl for
that.
Regards,
Lars.
Thanks,
James
