[mythtv-users] video capture cards all stopped working!

I've used mythtv for several years with no problem.  But I was running
out of disk space, and decided to upgrade the hard drives and the OS
(Fedora) at the same time.  So I installed Fedora 11, then copied
everything over from the old hard drives.  But my video cards don't
get a signal any more!  I haven't changed their setup physically, and
the configurations should all be the same, since I just copied them
from the old drives.  The weird thing is that I got the capture cards
working briefly just after getting sound to work with alsa again.  But
several reboots later (for other issues) and I've noticed that the
latest recordings aren't working, and I can't view TV any more.  Is
there anything that's changed from Fedora 8 - Fedora 11 with respect
to sound or video that would cause my old configurations to not work?

Playback on old recorded shows works fine, including audio.  But I do
get the following message when KDE starts up:

"KDE detected that one or more internal sound devices were removed.
Do you want KDE to permanently forget ab out these devices?

This is the list of devices KDE thinks can be removed:
Capture: Default
Capture: PulseAudio Sound Server
Output: Default
Output: PulseAudio Sound Server


I have three cards (Air2PC, DViCO Fusion HDTV 5 Gold, WinTV PVR 250),
and I have copied the appropriate firmware files into place under
/lib/firmware.

I do get quite a few of the following errors in dmesg:

ir-kbd-i2c: i2c IR (FusionHDTV) detected at i2c-3/3-006b/ir0 [cx88[0]]

But all the cards seem to be recognized by lspci, with the following output:

Any help would be greatly appreciated!
