Checked on my 40d6530 Support menu and it says the software version is 1012 and also says there is no update available when I try to update. Not sure if this Software is the same as firmware, which the Samsung website downloads says the latest firmware is T-GASDEUC-1018.0  available Jan 2012. So what does all that mean? Have I got the latest firmware? If not why not? And how do I get it?
