Yes I do have every all 53 Barnaby episodes on my Youtube channel. I was amazed when I came across a Polish internet TV channel that not only had every Barnaby episode but also every episode was digitally remastered. Episode 31 'Welcome Spring' which I thought was lost forever was there. The missing half of episode 23 'In Expectation' was there. A missing scene from the start of Episode 25 was there. Nearly all the episodes that had missing starting/ending credits had them restored. I was even more amazed when I found a way to download all the episodes! So what I've now got on my channel is the series in it's entirety with a complete set of English subtitles.
Though it's much more complete than the BBC version Barnaby fans will still always want to see the BBC English dubbed version as well as it's what we grew up with and loved.
In my email to the BBC I did mention possible copyright issues but their 'not commercially viable' reply was just a one liner and maybe they didn't have time to discuss the reasons.
