I don't know if anybody of you has managed to get the HD version, but after some googling I've found what it seems to be a 720p mkv version of this documentary: link link
Is anybody so kind to test this links? I can't at this moment.
Thanks for everything.
Can anybody tell me how to extract the subtitles from the DVD? It's a shame the mkv file doesn't have subtitles...And how can I merge them into the mkv file?
Thanks in advance
Correct me if I'm wrong but wasn't this filmed in standard definition and then merely upscaled for HD rebroadcast? Because if that's the case then there's no point in downloading the HD version as the upscaling interpolates the missing pixels - all you get is a biger file.

Yes you're right but on fact much of the footage shown there is from vhs sources so even the standard definition is "upscaled"
Anyway with this HD (Upscaled of course) files i can make sure about the dvd i will made with this files will has the best quality possible.
This is a transcoding of the original broadcast.
The size of 1.5 GB tells you that there is a lot of compression and loss of quality.
I don't think this will give you the best possible DVD.
You'd need to work from a losless recording.

Since the "bbc hd logo" is in the video i can be almost sure is (at least) the hd broadcast... the compresion also depends of the codec... mkv allows more quality in a minor size...
A true losless recording of this (a raw file) must be over the 60 gb aprox.
so as i said is one of the better options (availbles at the moment of course)
-But yes, you're right the compression losses the quality-
Cheers!

Don't know how you get to 60 GB but that is far from the truth.
I have a 40 minutes satellite stream capture from BBC HD of a Coldplay concert and it's 2.7 GB large so a stream capture of one one hour part would be about 4 GB large.
Also BBC HD transmits in 1080i.
I can't imagine how the quality of the DVD authored from a 1.5 GB 720p can be better than a direct MPEG2 capture from BBC2 whose size is even larger than 1.5 GB.
And you won't have the BBC HD logo in the corner....

Out of curiosity,
I recorded from BBCHD via a freeview box RGB scart out (downscaled) to a dvd recorder RGB scart in set at one hour quality mode.
I used nearly a whole dvd for one hour. No sub -titles recorded.
Video quality wise how would this compare, better or worse?

Your approach is quite common.
The problem with it is that the scart RGB is still an analogue signal and there will be loss in the DA conversion.
Even when recording in the highest quality on your dvd recorder, you won't be able to make up for that.
The only way to be certain that no quality is lost is to record the stream digitally on the box and only few boxes give you unrestricted access to this.
As I mentioned before the size of the HD recording would be about 4 GB, so with the proper box you can make a perfect HD capture and it will even fit on a DVD (but you'd need something better than a DVD player to view it).

Thanks for explaining Frank.
I'm still a bit confused about which is technically the best copy to keep, I suppose it boils down to personal choice.
At the very start of the Satellite SD broadcast Part 1 where 'Wembley Stadium 12th July 1986' is written at the bottom of the screen I can notice a fuzziness around the letters.
On this HD share and also on my HD recording the letters are crisp and clear, so for me the preference is with the HD versions, even though there is a logo.
I think we have become used to the the poor quality of SD transmissions, HD is really how SD should look in my opinion.
This is even apparent on a CRT TV.
