Hello Remco,
This is an issue related the template overrides.
Depending on the overrides and the classes used you can probably use this code snippet as a base.
.itemVideoBlock .avPlayerWrapper { position: relative; width: 100%; height: 1px; padding: 0 0 56%; max-width: 1000px; max-height: 562px; }
.itemVideoBlock .avPlayerWrapper .avPlayerContainer { min-width: 100%; }
.itemVideoBlock .avPlayerWrapper iframe, .itemVideoBlock .avPlayerWrapper object, .itemVideoBlock .avPlayerWrapper embed, .itemVideoBlock .avPlayerWrapper video { position: absolute; left: 0; top: 0; width: 100%; height: 100%; }
You can also dump or change the .itemVideoBlock class with the prefix your template uses.
