Ok, after 3 hours of troubleshooting this I'm about ready to throw in
the towel. It is beyond me why a hardware swap would cause this. Some
additional strangeness.... When I use the liveusb none of the lvm
commands have any problems finding anything. I'm able to mount, read,
write, everything. When I boot, nothing in my grub.conf specifies
VolGroup00, in fact it's referenced by UUID. So if the initrd can't
find VolGroup00, then how does it know what's it's called?

This is infuriating! Not only is this the second time I've had this
problem but I REALLY don't want to rebuild my mythtv box from scratch.
