No embedded video with NextGEN Gallery?!

I’ve encountered a problem with NextGEN Gallery.

version: NextGEN Gallery v1.5.0 Release candidate 1

After activating the NextGEN Gallery plugin, all my embedded videos (embedded through direct embedding code) are disappearing from the posts. Deactivating the plugin is resolving the problem.

Is this a bug or do I have to hack some settings?

Please help!
