The HD rip from the (standard definition) DVD and episodes merge were done together in one step to preserve quality. Ripping in HD, even from a Standard Definition DVD, means that when it is uploaded to YouTube, YT automatically allocates better audio to it.
By the way, its surprising, but all these 6 episodes on a single BBC DVD - can be bought from some sellers on Amazon for as little as 1p plus postage!
