It's not ideal that MythTV is setting DTV_DELIVERY_SYSTEM to 0 and I have filed a bug against this. But that doesn't change the fact that the original patch significantly changed user parameter handling for no significant benefit. MythTV is probably the biggest client of v4l and will greatly hinder users upgrading to (Myth)Ubuntu 12.04 or Fedora 16 both of which use Linux 3.x. -- Lawrence -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
