Thanks, it's nice to know I'm not the only lazy.

Could somebody test https://github.com/inaes-tic/mbc-playout/commit/6f42a2385c215333dfadae7fcd3b47d2b4219d39 and confirm that it saves repeated medias in a playlist?

It's mostly like this one but skips the _id generation, I'm not really sure why it wasn't working before.
