Intro
Here is a video from 1997.  Ahmadis don’t seem to have any inclination to visit the tomb and make videos.  Not even the Kashmiri-Ahmadis who live close by.  Nonetheless, the video is posted.

MGA and his team lied about the discovery..here is some data that they have posted

“””Ahmadiyya literature states that one of Ghulam Ahmad’s disciples, Khalifa Nur Din (or, Noor al-Din) of Jalalpur Jattan, District Gujrat, spoke to him about a tomb in Srinagar that was said to be the tomb of a prophet named Yuz Asaf. Ghulam Ahmad instructed him to do some further research into the matter. Nur Din went to Srinagar and stayed there for about four months. He collected information and also obtained the signatures of 556 inhabitants who attested that, according to their traditions, the remains of Jesus Christ lay in the Roza Bal.[7] He also brought back a sketch of the Roza Bal. Thereafter, Ghulam Ahmad decided to send one of his followers, Maulvi Abdullah, to Kashmir to investigate this tomb. Maulvi Abdullah arrived in Kashmir, conducted his investigations, and wrote back to Ghulam Ahmad about his findings. Ghulam Ahmad then published a poster that contained Maulvi Abdullah’s letter, as well as Maulvi Abdullah’s sketch of the Roza Bal.

Ghulam Ahmad began studying the local traditions of the people of Kashmir, both oral and written, and discovered that these traditions, as mentioned in the letter from Maulvi Abdullah, referred to the Roza Bal as the tomb of Nabi Isa (Prophet Jesus). According to this information, the Muslims in that locality did not believe Jesus to be in heaven, as was taught by the orthodox clergy. The Ahmadiyya publication, Review of Religions, recorded this belief in its October, 1909 edition.[8]“””
