I have all the available DVD's that Ray Mears sells. The 2004/05 series are excellent! They play fine on my DVD machine which is an Akai.
They also play fine on the computer. For some reason, computer DVD software will play any format DVD.
I bought my Mears DVD's from a seller on Ebay, which was the simplest way to get it accomplished.
