Thanks for your advice guys but I seem to be having some senior moments here as I can't find anything about the filter when on You Tube so how do you put a filter on?

I would have thought there would be an easy way to specify exactly what you want to search for but it seems that the result will always be mixed up with other things which are similar.

I can find all the Tyros5 stuff but it's just that it's mixed up among other irrelevant things and I wondered if there was a way of filtering them out

I think You Tube is one of the most useful sites on the internet but a good search box would be an enormous benefit & time saver.
