It may be a MythTV bug to assume there ought to be an xvmc-blit renderer; perhaps there is one for other XvMC-capable chips but afaik there's only the Xv renderer with openChrome. The above output shows the best possible fallback anyway, so is nothing to worry about. The gotcha for many - myself included - was the default fallback to OpenGL rendering instead of Xv, which the above bugs cover, but Udo doesn't seem to be having that problem. I found the simplest short-term workaround for the fallback to OpenGL is to launch mythfrontend with LIBGL_ALWAYS_INDIRECT=Y in the environment.
