Try 'yum downgrade <list-of-apps>'.

Thanks, Patrick. After navigating a few circular dependencies, your
suggestion allowed me to downgrade to the 0.22-2 versions of the myth
applications. (Maybe that's what I ran last, instead of my claimed 0.22-1.)

However, I'm getting the same error message when launching mythfrontend. I
am reading various posts from mythtv discussion groups, but they haven't led
to a solution yet.

Can anyone provide me any advice for identifying the root cause of this sort
of problem. mythfrontend is spewing information to the terminal, but I
don't know how utilize it. I feel like I should try to trace what libraries
are being loaded, or something like that.

Thanks,
Mark

I have no experience with myth tv, but how about eliminating
misconfiguration as the cause? You could try creating a new user and
running from there ...

Open source is the future. It sets us free.
