When u connect your iphone to the computer, u should be able to locate the vlc on the apps tab, scroll down to see the sharing apps, double click on the vlc there, drap and drop your videos in the right side panel. Now you should be able to play the video from your vlc in your iphone. In case you can not locate the vlc on your itune in app tab, remove and reinstall the vlc again directly from application store in your iphone and after that try syncing again. Remember to restart your iphone after removing the vlc before installing it again.
