Using RTMP Streaming & Creating a Playlist

My test page: http://www.marcobronzini.com/test/
I have a Pro account through this client.

I used to be able to add in videos to a playlist I created within my WordPress site. However, I am currently not able to add any new videos through the playlist but I was able to create them via this forum topic:

I’ve seen people having issues with the latest version of WP. Is there anyway I can still use my JW Player plugin / playlist system or do I have to rely on the shortcode I got from the above link?

Thanks,
Brian
