I was meaning to post a reply to this but it slipped my mind.

I'll certainly keep an eye out for the "years" tapes in charity shops; you can normally buy VHS tapes for less than a pound each in these sorts of places.

So all of the available stories are to be released on DVD? I remember reading somewhere on the DW restoration team website about the use of denoising filters because MPEG-2 didn't handle analogue noise very well. So why not put the episodes out on BD in standard definition AVC?

I also remember reading that the DVD of the 1996 movie was a botched IVTC, with blended fields all over the place. Is this true? (I know I could always Google it, but I can't be bothered right now). If this is the case, then a Custom DVD with the film frames reconstructed (Avisynth SRestore?) would be a useful first step before attempting any edits.
