Upgrading to MythTV 0.19, kernel 2.6.16.20, and ivtv 0.6.2, I ran into
a problem.
With no consistency, the PVR-250 card would be either /dev/video0 or
/dev/video1.
The pcHDTV card would sometimes get /dev/video0 first, so that MythTV would mark
/dev/video0 offline/unavailable.
Here's what I did to (more or less) assure that /dev/video0 would be
the PVR-250.
In /etc/rc.d/rc.local, I added commands to do these steps:
- remove all /dev/video devices . . . . . . . . rm -f /dev/video*
- unload kernel module ivtv . . . . . . . . . . rmmod ivtv
- re-load kernel module ivtv . . . . . . . . . modprobe ivtv
- sym-link /dev/video0 to /dev/video1 . . . . . ln -s /dev/video1 /dev/video0
This works even if the PVR-250 does NOT get /dev/video1 assigned to it, because
the sym-link just fails. The device, /dev/video0, is already assigned
to the PVR-250.
Of course, this may not work for ALL PVR-250/pcHDTV combinations. Here is the
specific configuration where it worked for me:
- Motherboard . . . ASUS A7N8X-E Deluxe
- PCI Slot 1 . . . . -------------------
- PCI Slot 2 . . . . pcHDTV HD-3000
- PCI Slot 3 . . . . PVR-250
- PCI Slot 4 . . . . -------------------
- PCI Slot 5 . . . . AirStar-HD5000
There are (no doubt) other solutions to conflicts such as this one. I just
wanted to document my experience, since it seems to have solved the problem.
