I hear it often on tv but cant get the meaning of it.

According to our dictionary-

ne olur/olursun! Please! (said imploringly).

Turkish speakers will probably have other interpretations too.

 As a Turkish speaker I think you are on the right way, sonunda hanýmefendi. 

A Turkish song by Sezen Aksu:

Geri dön, geri dön... Ne olur geri dön...

(Come back, come back... Please come back...)

Uzanýp tutuver elimi bir gün...

(Wait for translations)

Utanýr diyemem, ne olur geri dön...

(Wait for translations)

Thank you

As others already said ne olur/ne olursun means: please, oh please, won´t you please, pretty please, etc.

Here´s some examples in sentences:

Ne olur býrakma beni. 

Please don´t leave me.

N´olur bu konu üzerinde daha fazla durmayalým.

Oh please, let´s drop the subject.

- Özür dilerim, bu akþam sizinle sinemaya gelemeyeceðim.

I´m sorry, I won´t be able to come to the movies tonight with you.

- N´olursun gel, sensiz sinemaya gitmek istemiyoruz. 

Oh do come, please, we don´t want to go without you.
