Ok so my fathers mythtv box running .23, 2 days ago was running fine.
Tonite he calls me and says mythtv isn't recording. I go up, information
says recorders has an error. I look in the mythtvbackend log, i see:
Channel(/dev/video0)::Open(): Can't open video device, error "Permission
denied"
Channel(/dev/video1)::Open(): Can't open video device, error "Permission
denied"
Channel(/dev/video2)::Open(): Can't open video device, error "Permission
denied"
Channel(/dev/video3)::Open(): Can't open video device, error "Permission
denied"
I did some searching and say and error with pvr150's and a udev fixing it.
However, both of his are pvr500's. I did try that fix but it didn't work.
The weird thing is, once X is loaded, if I ssh in and run:
sudo service mythtv-backend restart
Everything works fine.
He hasn't done updates (he doesn't without me) in those 2 days.
The permisions on /dev/video0-3 is
crw-rw----- root video
where video has mythtv/hisusername as part of the group.
The udev rules made it:
crw-rw-rw- root video
But again non of this fixes mythbackend running correctly on bootup. I have
to VNC/SSH in and restart the backend, but once I do it works fine.
So if anyone could shed some light on this for me that would be great. I do
have autobuilds for mythbuntu enabled, I believe he's running 25368. Please
help me out here.
