If you want to find out who said what and when on any and every Doctor Who story, go Chrissie's Transcript Site. It's AMAZING! It tells every line in every Who story, including the missing ones, and a description of the action when necessary, from classic and new, all the way all the way from the first Doctor to the present Twelfth. It also include The Sarah Jane Adventures and Torchwood, plus ever Star Trek series and Andromeda. It may not be the whole experience, as you can't see the characters or moving action, but if you can't find a certain classic DVD or afford the ridiculously priced NuWho DVDs (where I live they cost 80 bucks per season!) go to this site. You won't be disappointed.
