Also seeing this with an old onboard Radeon 9100 in Fedora 8. It's been
working using GL sync for years on a heavily-hacked FC3 setup. Did the
OpenGLVideoSync API change in the latest Fedora X server?

X Window System Version 1.3.0
Release Date: 19 April 2007
X Protocol Version 11, Revision 0, Release 1.3
Build Operating System: Fedora Core 7 Red Hat, Inc.
Current Operating System: Linux xxx 2.6.23.1-49.fc8 #1 SMP Thu Nov 8
21:41:26 EST 2007 i686
Build Date: 17 October 2007
Build ID: xorg-x11-server 1.3.0.0-33.fc8

This is with mythtv 0.20.2 using Axel's RPMs.

Cheers,
Wilf.
