PROBLEM SOLVED I downloaded, compiled, and installed the latest DVB drivers and now everything works great with MythTV0.19. I may have had these driver problems before, but for some reason they didn't affect the channel changing/locking with myth0.18 - strange. I'm happy now that everything is back and working after the upgrade.
