I had simliar trouble. My solution was to remove the xorg.conf line
causing glx to load, and use the frontend setup to disable the various
OpenGL effects. 

I think my inability to use Picture-in-Picture may be related to my
abandoning glx and OpenGL, but I can live with that for now. I haven't 
tried playing a DVD, but Live TV, Watch Recordings, Image Viewer, 
MythWeather, MythFlix, and MythMusic all work with glx disabled.

FC 4, Athlon64 running i386, Jarod's instructions, FX5200 AGP card with
the DVI output and basic XvMC support in the frontend

Previously I had 0.18.1 running on a system with a Hauppauge PVR-350
S-video TV-out for the frontend app and X in general, and everything
including P-i-P worked pretty well.
