yeah most stories are 4-6 eps long, sometimes in the early days 7-10, not all those i have were bought seperately, some were released as box sets, the first 3 stories (unearthly child to edge of destruction) were released in a boxset called "beginnings" keep of traken, logopolis and castrovalva are chronological and were released in a box new beginnings, silurians, sea devils and warriors of the deep, while not being chronological, all feature the sea devils and silurians (brother races and warriors combines both) as a set called "beneath the surface" and so on.
actually if you look around you can actually find some good deals, i never buy them on release as they are around the £15 mark which is ridiculous, but a lot of ebay shops sell them at £4.99 brand new with £1 or £2 postage so that's how i've got a lot of minemuch better value for money i think.
The lost in time boxset is 3 discs and contains all complete episodes of incomplete hartnell and troughton stories that still exist less then 50% (so tenth plant isn't there as only one episode is missing, though i believe theres another reason for its abscence that cosgrove hall are reanimating the final episode like the invasion) and frankly its a really good set, the extras are existing segments of stories that are in some cases completely missing in their entirity.
Jynks, the ones your thinking of have been released in complete boxset only, trial of a timelord was released last week as a complete boxset, and the key to time (tom baker) was released complete about 2 years agoin a big 12 or something disc boxset, i would say the reason for non chronological release is so theres dvd releases to cater for fans of any doctor, currently the doctors with the most releases though are t baker and davison.
i think i know another way to do commentaries, i was thinking about it last night, and when you rip the vobs it contains all audio tracks for that episode, then when run through dgindex to prepare it for gknot loading it rips all the audio tracks, commentaries included, to ac3 files, then i can just do audio processing only in gknot or something similar to mp3, personally though i don't really care about commentaries most of the time so i probably wont get round to doing them or at least not til ive ripped every ep properly first
and i know what you mean about colin bakers pompousity, in revelation of the daleks (watched yesterday) he tells peri she eats too much and shes fat
, when frankly shes nothing but hot
