Delete Real Player History on S60 1st and 2nd Edition

As you see in the left picture, if you'd ever opened a video on your built-in RealPlayer in S60 1st and 2nd Edition phone, you should see the most recent clips that you had watched.

If you want to delete it from history you can't just delete it from the application. You need a third party file manager that can see the hidden folder and file in your S60 1st and 2nd Edition devices. Then, go to C:\system\data\, find a file named mediaplayer.dat, and delete it. Now, if you check again your RealPlayer, you mustn't see most recent clips option again like the picture in the right.

I found this usefull triks from Symbianize by GSM_BLUE. Now, I don't know how to delete it on S60 3rd Edition. Any info?
