How to switch between files/streams?

[GEFORCEXTREME]

Hi, I'm thinking of this, playing a media file, then get the postion/time, then play another media file from that time.
I tried using libvlc_media_player_play, libvlc_media_player_set_media and such. It works, however the first media file is closed first before the 2nd media file is played.

Is it possible to switch without closing the video output on the screen? Thanks.
