Apparently Fujifilms latest firmware for their great X-Pro 1 is Faulty. Fujifilm have made a statement whiuch seems that the issue may indeed me a little more serious then first thought
We are very sorry that we have found a malfunction on the movie function in the upgraded firmware version 3.00 posted on 23 Jul 2013. We are improving the firmware and we will post it again once we complete the improvement. We deeply apologize for your inconvenience which this may cause.
Please contact your local support center if you have already upgraded your X-Pro1 with the version 3.00.
So if your one of the unlucky people who has already updated their firmware get to it. I on the other-hand am always behind the 8 ball and have not updated my Fujifilm X-Pro 1 .... Lucky Me
