[mythtv-users] Second PVR not seen my MythTVSetup, possible permission problem?

Here's a new one for me:
Trying to add 2 PVR-150s to a newly built machine.
The first card (/dev/video0) works just fine.
I can't add the second card, usually I can just scroll through the available
devices, but I can only get /dev/video0. If I manually set it to video1 it
says it can't open the card.
Boot logs show both cards being initialized normally.
Both devices appear to be there:
ls -l /dev/vid*
lrwxrwxrwx 1 root root 6 2009-03-10 17:41 /dev/video -> video0
crw-rw----+ 1 root root 81, 0 2009-03-10 17:41 /dev/video0
crw-rw---- 1 root root 81, 1 2009-03-10 17:41 /dev/video1
crw-rw----+ 1 root root 81, 24 2009-03-10 17:41 /dev/video24
crw-rw---- 1 root root 81, 25 2009-03-10 17:41 /dev/video25
crw-rw---- 1 root root 81, 32 2009-03-10 17:41 /dev/video32
crw-rw---- 1 root root 81, 33 2009-03-10 17:41 /dev/video33
This looks correct to me, except:
I don't understand what the "+" is after the video0 device. I don't think it's
the suid bit, or any of the things I'm familiar with.
But the device with the "+" works, the one without it does not. I'd just add
the "+", if I had any idea what it might be.
This is a Fedora 10 machine, does Fedora handle permission listings
differently somehow?
I can cat /dev/video0 or cat /dev/video1 (as root) and get data dumped as
usual from both devices.
It's not an interrupt contention problem:
cat /proc/interrupts
CPU0 CPU1
20: 1229 131882 IO-APIC-fasteoi ivtv0
21: 0 402 IO-APIC-fasteoi ivtv1
Any ideas appreciated, as usual.
