Received this disc today. Not watched it yet but on looking at the disc it has a huge blemish emanating from the centre of the disc all the way round to about half the depth of the disc. Not sure if it will cause any playback problems but has anyone else noticed this. First disc I've noticed like this. Sure it can't be disc rot as it is brand new (seal just opened 10 minutes ago. You can clearly see it on the above picture. Any ideas. Thanks.
