Description of your issue, suggested solution and other information

Visiting the URL from above with the web browser works just fine in terms of playback. Previously I had no problems with downloading videos from that very site (www.cda.pl)

Thanks.

Thanks for the example. Birthday verification on CDA will be supported in the next version.
