I bought this set from Canada before the series was released on DVD in the UK, and I wish I hadn't bothered. Don't get me wrong, I love this series and had every episode on VHS, I just wanted an upgrade and I didn't get it. The episodes are brilliant, but I already knew that, but the transfer to DVD is shocking. The sound is muffled and the volume variable, and the picture quality is dreadful. It looks like they were transferred from someones home recording - just awful. I later bought some of the R2 UK versions which were much better with crisp pictures and clear sound. There are a number of versions available on DVD - DON'T BUY THIS ONE.
