I don't know what's happened but when I select a video file from my playlist it plays as a different one! The URL is correct.
I only found out as my 10 year old son selected what he thought was a children's video but when it played it was something else! There were a few select words he shouldn't be hearing so that went off very quickly!
This has happened since Navi-X was updated. But I had saved an older version and that is doing the same too. I've not altered my playlist.
