I was quite taken with the first 3 hours' worth shown on Sky; much better than I expected. The DVD is quite cheap on Amazon (£8.97) but the site gives no technical details at all. Does anyone have this? Any comments on picture quality and particularly on sound format (5.1 or stereo etc) would be appreciated. The PQ on Sky was OK but a decent DVD would be preferable. The series does seem to be expensively put together so hopefully the DVD is too.
