I reached out to vu support and their response was the best i have experienced. They understood the issue that ntfs is not working for apps like vlc etc. They took a few days and mailed me an ota update. After installing the update via usb, ntfs is now working natively for my 50 inch vu premium tv.
Hats off to vu.
Hope they roll out ntfs suport for all soon.

Could you please share the upgrade files with me? I am facing the same issue.
