I think media should be had a option to log or not log to database.
Now we have log option in Display profile only.
In some case, I have mediaA, mediaB and mediaC.
I want to log mediaC only but all of them played on same Display (with log option). Then I have more trash/un-wanted log (from mediaA and mediaB) in my database. And day-to-day, month-to-month, my database will increase size.
Sorry for my bad explains. Hope you will understand my opinion.
