Just wondered if anyone can explain why the figure for the amount of views on my vids is different when seen from the site's main Videos page, compared to the figure seen on "my scenes" page?

You're going to have to be more specific. If I look at
https://umd.net/profile/i/mudsprite/section/videos?sortby=thedate
it says 5 views for "Triple Mess Delight 3"

If I look at
https://umd.net/videos?sortby=thedate&start=0
It ALSO says 5 views for "Triple Mess Delight 3"

Where are you seeing a discrepancy?

One is the page views, and one is the actual number of "plays" the vid got. A couple of weeks ago I updated the verbiage on your My Scenes page to make that hopefully more clear.
