[mythtv-users] channels/DVB card go missing

[mike at grounded.net]

This is just a snipet of the mythfrontend log.
Last night, things were working just fine.
This morning, I turn on the TV and tune to a W5 channel and I get a black screen followed by the FE exiting back to the desktop.
Looking at the log, I see that several things are happening so I'm not sure what to do first.

-Analog is not attached to anything
-When I tune to a W5 channel, it breaks myth and goes back to desktop
-When I tune to a W5 channel, I notice that the DVB side is no longer being seen in the mythtv-setup screen. It is there just before I change channels, then cannot be seen anymore.

Short of deleting all cards and doing everything over again, I thought I'd ask about this first.
