Your first post, so welcome!
For me on that page there is no video, just an audio podcast. But as far as I can tell, it is working properly (32-bit Vivaldi v188.8.131.52 on 32-bit Win7).
If you're using Technical Preview 2 (v.184.108.40.206) as most new users are, try updating to the most recent Developer snapshot.
Vivaldi is developing rapidly and there have been numerous bug fixes and feature improvements since Technical Preview 2. Developer snapshots since then have generally been as stable, if not more stable, than TP2.
