Drupal and Organic Groups

Hi all,

I have installed KalturaCE and integrated it with Drupal with Organic Groups installed.

I have configured OG so that when an allowed user posts a general content type node (e.g. a page) to a defined group, that node is automatically published in that group only and is not publicly available.

The problem arises when the user posts a Kaltura media node because it is published as 'public' by default, no matter which group the user belongs to.
Thus, once the node has been created, I have to edit it, clearing the 'public' checkbox and checking the one related to the correct group.

How do I make Kaltura module work as expected?

Kaltura CE 1.0
Drupal 6.15
Organic Group 2.0

Thanks
