In case of s40 mobiles we can only open one app at a time>>In many sites they have posted some of the tricks which will never work on Nokia X2-00 and some other mobiles.
I have found a working trick using UC BROWSER 8.
1.download UC browser from here using mobile.
2.Install it >u can use this high speed browser and also other app at the same time.
3.Make a new tab
4.In the address field type: rtsp://anything.com.
5.Your media player will open.just pause it.
6.go to madia player menu.
7.From here you can play videos and music.OR.You can use built in browser from media player menu>>options>>goto >>type your address................
