I tried your method but for some reason the url that YouTube.uk gave me started with
http://uk. etc. This worked when I tried it at first but failed to work from Pixalo. Eventually Snap2Photo spotted the
uk and suggested changing it to
www and it then worked.
Exactly the same thing happened when I uploaded a second AV to YouTube but I was prepared and altered the
uk to
www and it worked fine. If anyone else in the UK has problems with their AVs uploaded to YouTube.uk then this might be the solution.
